php unicode string

2011-08-31T10:21:00.001-06:00

Have you ever wanted to express unicode code points in a php string

$string = "Hello World \u4f60\u597d\u4e16\u754c";

(which is...)

$string = "Hello World 你好世界";

Try this:

$string = ustring("Hello World \u4f60\u597d\u4e16\u754c");

Geany Find in Files Dialog

2011-05-20T11:16:00.001-06:00

I opened the geany Find in Files Dialog and it kept defaulting to ISO-8859-1. It kept bugging me cause I wanted it to default to UTF-8

Turns out... in the source code of Geany 0.20 says this:

/* set the encoding of the current file */
if (doc != NULL)
    enc_idx = encodings_get_idx_from_charset(doc->encoding);
gtk_combo_box_set_active(GTK_COMBO_BOX(fif_dlg.encoding_combo), enc_idx);

So my problem was I had an ISO-8859-1 file open... then when I went todo CTRL-SHIFT-F, find in files, it defaulted to the charset of the file that was already open. All I had to do was change the encoding of my file (that was already open) to utf8 and the find in files defaulted correctly.

Java Servlet 2.5 API javadocs for Tomcat 6

2011-02-17T11:03:00.003-07:00

Oh my goodness, I am starting to dislike oracle. When I google for "java servlet 2.5 api docs"

The first link is:
* http://www.oracle.com/technetwork/java/javaee/servlet/index.html

and when I go to the page:
* http://tomcat.apache.org/tomcat-6.0-doc/index.html

it has a link to
* Servlet API Javadocs - The Servlet 2.5 API Javadocs.

But the link is a dead link that redirects to
* http://www.oracle.com/technetwork/java/javaee/servlet/index.html

ug.

Well I finally found out that javaee 5 uses servlet api 2.5 so this might work
http://download.oracle.com/javaee/5/api/javax/servlet/package-summary.html

But so might this:

utf8 in php5

2010-05-31T00:12:00.014-06:00

utf8_encode() and utf8_decode() are awful, because they only operate in the ISO-8859-1 (latin1) charset portion of utf8. Also, for reference U+ff01, the ff01 is called the code point.

Lets say I have a unicode character U+4f60 or 你, and I want to echo it in php.

http://www.fileformat.info/info/unicode/char/4f60/index.htm

PHP is not very utf8 friendly, in order to get to work, you have to be using a computer with the right language packs installed, edit the source file in utf8, make sure every page sends out header('Content-type: text/html; charset=utf-8'); and you may still need to echo the utf8 meta tag. And for good measure make sure the file is saved with a utf8 byte order mark. But how do you echo unicode if your source file can only be in the latin1 character set?

One way is to echo the code point. In java "\u4f60" represents the character 你. Not so in php. The best you can do is these:

<?php echo json_decode('"\u4f60"');?>
<?php echo html_entity_decode("你",ENT_QUOTES,"UTF-8");?>
<?php echo "\xE4\xBD\xA0";?> //already encoded in utf8

but there is another way, with 2 basic functions:

function utf8($num)
{
  if($num<=0x7F)    return chr($num);
  if($num<=0x7FF)   return chr(($num>>6)+192).chr(($num&63)+128);
  if($num<=0xFFFF)  return chr(($num>>12)+224).chr((($num>>6)&63)+128).chr(($num&63)+128);
  if($num<=0x1FFFF) return chr(($num>>18)+240).chr((($num>>12)&63)+128).chr((($num>>6)&63)+128).chr(($num&63)+128);
  return '';
}

function uniord($c)
{
  $ord0 = ord($c{0}); if ($ord0>=0   && $ord0<=127) return $ord0;
  $ord1 = ord($c{1}); if ($ord0>=192 && $ord0<=223) return ($ord0-192)*64 + ($ord1-128);
  $ord2 = ord($c{2}); if ($ord0>=224 && $ord0<=239) return ($ord0-224)*4096 + ($ord1-128)*64 + ($ord2-128);
  $ord3 = ord($c{3}); if ($ord0>=240 && $ord0<=247) return ($ord0-240)*262144 + ($ord1-128)*4096 + ($ord2-128)*64 + ($ord3-128);
  return false;
}

<?php echo utf8(0x4f60);?>
你
or you can convert back
<?php echo dechex(uniord(utf8(0x4f60)));?>
4f60

Also helpful:
function is_utf8($string)
{
  // From http://w3.org/International/questions/qa-forms-utf-8.html
  return preg_match('%^(?:
      [\x09\x0A\x0D\x20-\x7E]      # ASCII
    | [\xC2-\xDF][\x80-\xBF]       # non-overlong 2-byte
    |  \xE0[\xA0-\xBF][\x80-\xBF]    # excluding overlongs

There is no .deb in the ubuntu 9.10 rep for hamachi or quamachi. Have no fear, you can install it via the autopackage system. Just download the .package files and satisfy dependencies, and run the package files.

1. Go to http://code.google.com/p/quamachi/
2. download hamachi and quamachi, ex:
http://quamachi.googlecode.com/files/quamachi-0.4.1-1.package
http://quamachi.googlecode.com/files/hamachi-0.9.9.9-20.package
3. sudo apt-get install python libqt4-core python-qt4 pyqt4-dev-tools upx-ucl grep bash make
4. chmod 777 hamachi-0.9.9.9-20.package
5. chmod 777 quamachi-0.4.1-1.package
6. sudo ./hamachi-0.9.9.9-20.package

in the firefox-error console type the following:

rsync -C or --cvs-exclude

2009-09-11T09:51:00.008-06:00

rsync -C option excludes .exe files by default so if you want to rsync .exe files add in
--include=*.exe

Which filetypes does cvs ignore? Then.. which filetypes does rsync ignore ontop of the cvs ignores. From man pages (man rsync):

-C, --cvs-exclude
This is a useful shorthand for excluding a broad range of files that you often don’t want to transfer between systems. It uses a similar algorithm to CVS to determine if a file should be ignored.

The exclude list is initialized to exclude the following items (these initial items are marked as perishable — see the FILTER RULES section):

RCS SCCS CVS CVS.adm RCSLOG cvslog.* tags TAGS .make.state .nse_depinfo *~ #* .#* ,* _$* *$ *.old *.bak *.BAK *.orig *.rej .del-* *.a *.olb *.o *.obj *.so *.exe *.Z *.elc *.ln core .svn/ .git/ .bzr

then, files listed in a $HOME/.cvsignore are added to the list and any files listed in the CVSIGNORE environment variable (all cvsignore names are delimited by whitespace).

Finally, any file is ignored if it is in the same directory as a .cvsignore file and matches one of the patterns listed therein. Unlike rsync’s filter/exclude files, these patterns are split on whitespace. See the cvs(1) manual for more information.

If you’re combining -C with your own --filter rules, you should note that these CVS excludes are appended at the end of your own rules, regardless of where the -C was placed on the command-line. This makes them a lower priority than any rules you specified explicitly. If you want to control where these CVS excludes get inserted into your filter rules, you should omit the -C as a command-line option and use a combination of --filter=:C and --filter=-C (either on your command-line or by putting the “:C” and “-C” rules into a filter file with your other rules). The first option turns on the per-directory scanning for the .cvsignore file. The second option does a one-time import of the CVS excludes mentioned above.

modification to zetcode tutorial

2009-09-03T20:04:00.002-06:00

wxwidgets tutorial at
http://zetcode.com/tutorials/wxwidgetstutorial/menustoolbars/

has the line

wxBitmap exit(wxT("exit.png"));

I get the error in a windows compiler
"failed in wxToolbar::Realize(): invalid tool button bitmap"

the fix:
replace that line with

wxImage exitimage(wxT("exit.png"), wxBITMAP_TYPE_PNG);
wxBitmap exit(exitimage);

note:
don't forget to include #include
and call wxInitAllImageHandlers(); in your app init

wx widgets icon for your app

2009-09-03T19:12:00.009-06:00

in windows build a file call main.rc with the following contents:

aaaaaaaaaaaaaaaa ICON "application_icon.ico"
application_icon ICON "application_icon.ico"
#define wxUSE_NO_MANIFEST 1
// set this to 1 if you don't want to
// use manifest resource (manifest resource
// is needed to enable visual styles on
// Windows XP - see docs/msw/winxp.txt
// for more information)
#include <wx/msw/wx.rc>

the windows compiler sets the first icon to be the .exe icon... and the 2nd is referenced in the code:

Then in your Frame constructor

#if !defined(__WXMSW__) && !defined(__WXPM__)
#include "application_icon.xpm"
#endif
SimpleMenu::SimpleMenu(const wxString& title)
: wxFrame(NULL, wxID_ANY, title, wxDefaultPosition, wxSize(280, 180))
{

SetIcon( wxICON( application_icon ) );
...

you can use gimp to build your xpm and and ico files. If you rename your xpm file at all... edit it with a text editor and make sure the c string in it reads:
application_icon_xpm if the filename is application_icon.xpm

wxWidgets - rc file "wx/msw/wx.rc" not found

2009-09-03T19:09:00.002-06:00

using visual studio express 2008
with an .rc file that has:
#include "wx/msw/wx.rc"

Error: "wx/msw/wx.rc" not found

the fix:

Even though you have already set the include path for your whole project to include wxwidgets... you need to set the include path again for the .rc file. Select main.rc... go up to project properties and you will see a smaller menu, and a place to put the Include path again.

wxWidgets - No Image Handler Defined

use array_map to select 1 column out of rowset of php rows

2009-08-21T16:16:00.007-06:00

Given a series of rows of data (perhaps rows in a database, copied into memory), we want to extract only 1 field of data and put it into a comma delimited list. (or array to loop through).


$arr = array();
$arr[] = array('first'=>'jack','last'=>'smith');
$arr[] = array('first'=>'john','last'=>'williams');
$arr[] = array('first'=>'mark','last'=>'jesperson');
$arr[] = array('first'=>'vlad','last'=>'shuttleworth');

$f = array_map(create_function('$a', 'return $a["first"];') , $arr);
echo implode(",", $f);
//outputs:
//jack,john,mark,vlad

numbers from 001 to 999

2009-07-31T23:53:00.015-06:00

the numbers from 001 to 999


echo "<?php for(\$i=1; \$i<=999; \$i++){ echo sprintf('%03d',\$i).chr(10);} ?>"|php

The \ has to go before the $ character because $i can refer to the command line environment variable $i, so we escape it with \$i in order to pass it straight through to the php parser.

Cross Browser Compatible Javascript DOMelement function

2009-06-02T10:15:00.026-06:00

In the past... you had to do
//------------

var a = document.createElement('div');
a.setAttribute('class','myclass');
a.setAttribute('id','id_mydiv');
document.getElementById('otherdiv').appendChild(a);

//------------
to create a dom element... and it only worked in firefox. to get one that works in internet explorer you have to do:
//------------

var a;
try {
  a = document.createElement('<div class=myclass id=id_mydiv>');
}
catch(e) {
  a = document.createElement('div');
  a.setAttribute('class','myclass');
  a.setAttribute('id','id_mydiv');
}
document.getElementById('otherdiv').appendChild(a);

iPod Touch

2009-05-28T21:08:00.004-06:00

For the economically minded consumer who doesn't need the phone, cell phone camera or gps, but has wi-fi and just needs a solid pda get the ipod touch 8GB 2nd generation. I got a refurbished one for $179.00, and for my chinese work, it is amazing. It does chinese stroke recognition, there are free chinese dictionary apps, skype is came out with a free app as well.

Accessories:

However to use skype you need a microphone for your ipod touch. The charger that comes with it charges off of your computer so if you go on vacation you will need a wall and/or car charger. You will also want to get an audio/video cable set so you can project videos onto your tv set.

JVC Everio

2009-05-28T20:56:00.004-06:00

The JVC Everio offers several models. Probably one of the most appealing thing about the everio is that it records to MPEG2 (uncompressed DVD) instead of MPEG4 (highly compressed like a digital camera's video). Its resolution is also DVD resolution 720x480, however it is more like tv quality (interlaced video) and less like digital HD.

It is offering a JVC Everio GZ-MS100 model right now for $180, which is really nice, considering that flash memory will continue to get cheaper. So instead of paying $350 for a hard drive camcorder... get a flash based one, and get a 2GB SD card. In a few years 8GB and 16GB SDHC cards will be cheap, and you can just use that for your camcorder.

For accessories it might be a good idea to get an extra JVC Everio battery. Because even if you have space to record 4 hours of video on your SD card, it doesn't mean your video camera battery will last that long

nohup command

2009-05-26T11:21:00.016-06:00

nohup ./myscript.sh>log_myscript.log 2>&1 &
tail -f log_myscript.log

nohup ./myscript.sh>log_myscript_`date +%Y%m%d`.log 2>&1 &
tail -f log_myscript_`date +%Y%m%d`.log

`date +%Y%m%d` - grabs current date, inserts it into filename
nohup          - script run even after terminal/ssh session ends
>log_myscri... - captures output to log file named log_myscr.. 
2>&1           - outputs stderr to stdout
&              - makes it run in the background
tail -f        - watches log, CTRL-C will not stop script

rsync windows to linux

2009-05-24T20:34:00.003-06:00

Scenario: windows has your user data and linux is your backup server.

1. compile cygwin... use the following, place them in your path
(c:\windows\system32 or c:\server\bin\)
rsync.exe
ssh.exe
ssh-keygen.exe
cygcrypto-0.9.8.dll
cygiconv-2.dll
cygintl-8.dll
cygminires.dll
cygpopt-0.dll
cygwin1.dll
cygz.dll

2. on the windows machine, run ssh-keygen at the command promptit will create a file
C:\Documents and Settings\user\.ssh\id_dsa.pub

3. copy C:\Documents and Settings\user\.ssh\id_dsa.pub to the linux machine... then authorize it:
mkdir ~/.ssh
cat id_dsa.pub >>~/.ssh/authorized_keys2
mkdir ~/backups

4. If you want to rsync F:\apps\myfolder then save the following as... backup.bat
-----------
F:
cd \apps
"c:\server\bin\rsync.exe" -arv -e "c:\server\bin\ssh.exe" myfolder user@linux:/home/user/backups/
-----------

gpg crontab

2009-05-19T16:44:00.003-06:00

1. executing in crontab provides a different set of environment variables, so the --homedir is needed to specify which keyring to use. In the example below, we use root's keyring.
2. --batch is necessary for crontabs because it tells gpg there is no user to interact with
3. 2>&1 is useful because it redirects stderr to stdout so you can better debug any errors you may be having
4. -d is for decrypt. in this case we are decrypting on a cron job

/usr/bin/gpg --batch --homedir /root/.gnupg --passphrase mypassphrase -o /home/output.csv -d /home/input.csv.gpg 2>&1

javascript debugging in ie

2009-03-11T11:19:00.009-06:00

Firebug rocks, and though there is a version for IE, it isn't the same. So in developing javascript heavy websites, it is always useful to have an IE brower around and debugging tools so you can figure out why your code is breaking in IE and not Firefox.

There are 3 ways to debug javascript in ie:
1. microsoft script debugger
2. visual studio .net
3. microsoft script editor (comes with office xp/2003)

Seeing as [2] and [3] both involve handing money over to micro$oft. We are left with [1]. The microsoft script debugger is no way related to the Internet Explorer Developer Toolbar

The Script Debugger is pretty sad but at least you can visually see what line of code your IE breaks on. It can still leave you scratching your head as to 'why' though. To enable it go to your "internet options" menu and hit uncheck the "Disable Script Debugging (Internet Explorer)" option.

Note to self: This breaks in IE7
var a = { width: 100, height :200 , };
While invalid syntax, IE7 should not be so delicate it gets tripped up by this. Allowing an extra comma in an array or dynamic object allows for cleaner code when generating javascript from another language.

please mount the unreal tournament play disc cdrom - ut2004 on ubuntu fix

2009-02-26T21:23:00.002-07:00

I was trying to install ut2004 on ubuntu and kept getting the message:
"please mount the unreal tournament play disc cdrom"

I think because ubuntu auto-mounts volumes, it mounts them in multiple places, somehow confusing the installer. The answer is to umount it... then manually mount it below as shown.

sudo apt-get install libgtk1.2
umount /media/cdrom
sudo mount /dev/cdrom /media/cdrom
export SETUP_CDROM=/media/cdrom
/media/cdrom/linux-installer.sh
... let it install ...
umount -f /media/cdrom

Note: installing libgtk1.2 is just to have a gui installer instead of console/ascii looking installer

it worked for me.

VMWare on supporting 64 bit guest OSes

2008-11-04T11:23:00.004-07:00

I wanted to play with a 64 bit OS once, so I installed VMWare to experiment with it. My box had a 64 bit AMD CPU, and was running a 32 bit linux OS on it. I didn't think I would be able to install a 64 bit VMWare guest OS on it, but it worked fine.

Later I tried this all again but on an intel 32 bit box, and it didn't work.

I just found a link that describes under exactly what conditions 64 bit guest OSes will and won't work:[kb.vmware.com].

Skype: Belkin Skype Phone

2008-09-22T19:13:00.007-06:00

One of the nice things about skype is that you can download it for Mac, Linux or Windows, so you aren't particularly tied down.

Skype is a DIY voip service. They offer a skype out unlimited subscription for canada and the usa (unlimited outgoing calling from your computer to landlines and cellphones) for $30. If you choose you can also get a phone number in whatever USA area code you want for another $30. I am sad that there still are no numbers available in canada. Because skype online numbers are available in over 20 countries at the time of this writing, i wouldn't be surprised if canada has extra red tape, which is preventing this.

So for the cost of $5 computer speakers, $5 computer microphone, an internet connection and $60/year ($5/month) you can scrap your $30/month landline. Don't forget to read the fine print, skype wants you to know that you can't use it for 911 calling, because the 911 operators have no idea where you are calling from. You could be online in europe and still take skype calls at your 801 usa area code through your internet connection. So... it is important to keep an old cell phone around. Even deactivated/non-sim card cell phones are required by law to be able to call 911.

My wife doesn't like using the computer for calling much, plus we don't want to leave it on 24/7 to take calls so we were thinking of getting the belkin skype desktop phone. This phone is a no computer required phone. It seems a little pricey considering it is just a phone... but understood what the skype phone really is, its pretty much an $80 computer with built-in microphone and speakers.

There are a lot of items for sale which replace your microphone and speakers... some usb phones, some cordless phones (comp req'd), other cordless phones (comp not req'd), and even wifi phones. Wifi is great... if you get a wifi hotspot anywhere you can make or take calls. I have heard the battery life on them isn't great yet... because it just like a minilaptop- but you can't turn the wifi network card off for power saving mode!

C++ : How to Launch a Background in Windows Program

2008-09-11T10:31:00.009-06:00

In linux it is easy to launch a background process at the command line with ampersand.

./app_to_launch &

In windows there is no easy command line suffix which will launch your program in the background. However it is relatively easy to code one up. If you install Visual C++ Express 2005, and the Microsoft Platform SDK (see configuration below) just compile this application as BKLAUNCH.exe and you will soon be able launch apps in the background from batch files.

I created an empty win32 project named BKLAUNCH, no precompiled header, and compiled the following code.

#include <stdlib.h>
#include <string.h>
#include <stdio.h>

#include <windows.h>
#include <shellapi.h>
#include <tchar.h>

int _tmain(int argc, _TCHAR* argv[])
{
    if (argc!=2)
    {
        printf("Usage:\n");
        printf("    BKLAUNCH.EXE [apptolaunch]\n");
        printf("    BKLAUNCH.EXE notepad.exe\n");
        exit(0);
    }
    ShellExecute(NULL, TEXT("open"), argv[1], NULL, NULL, SW_SHOW);
    return 0;
}

Once BKLAUNCH has successfully compiled, place it in a folder that is in the PATH. Now, go to Start > Run > cmd.exe [OK], and enter the following:

BKLAUNCH notepad.exe

You will notice notepad.exe is launched in the background, perfect for batch files.

Troubleshooting
If you are like me and use default settings, look under
Project > Project Properties > Linker > Input > Additional Dependencies
it will will have only kernel32.lib. When you compile there will be linker errors.

Because of the #include <windows.h> and #include <shellapi.h>
you need to add the following to your Additional Dependencies
kernel32.lib user32.lib gdi32.lib winspool.lib comdlg32.lib advapi32.lib shell32.lib ole32.lib oleaut32.lib uuid.lib in order to resolve the linker errors.

Microsoft Platform SDK Config
In order to use the MS Platform SDK in Visual C++ Express 2005, you have make the platform SDK visible to the compiler.

Go to
Tools > Options > Projects and Solutions > VC++ Directories > Platform=Win32 > Show Directories for=include files
Add to the list,
C:\Program Files\Microsoft Platform SDK for Windows Server 2003 R2\Include
(or wherever you installed the MS Platform SDK\Include)

Now, go to
Tools > Options > Projects and Solutions > VC++ Directories > Platform=Win32 > Show Directories for=library files
Add to the list,
C:\Program Files\Microsoft Platform SDK for Windows Server 2003 R2\Lib
(or wherever you installed the MS Platform SDK\Lib)

BASH: bad interpreter: No such file or directory

2008-09-09T08:42:00.003-06:00

-bash: ./execute.sh: /usr/bash^M: bad interpreter: No such file or directory

Dos text files use \r\n (0xD 0xA) as their end of line characters. Unix text files use \n (0xA) as their end of line character. What happened here is I had a file in dos text format, and tried to execute it in bash. the ^M you see above is saying "It wasn't expecting the \r character".

Solution:

use dos2unix

[user@linux1 ~] dos2unix execute.sh
dos2unix: converting files execute.sh to UNIX format...
