Create a ClickTag for your flash banner ad:

Action Script 2.0

Add  a transparent layer(MovieClip) on the complete Flash Movie area,  and write the script over the movieClip by Right click on the clip and select the Action from and add the script.

Action Script 2.0

on (release) {
 if (clickTAG.substr(0,5) == "http:") {
 getURL(clickTAG, "_blank");
 }
}

Action Script 3.0

Create an transparent MovieClip as same as the stage size and give a instance name as ClickTag(you can use other names). Write the following code in the action script window of the frame.

Action Script 3.0

// Get URL params
var flashvars =  root.loaderInfo.parameters;
// Convert to string format
var clickTAG=String(flashvars['clickTAG']);
// Add Event Listener to the ClickTag MovieClip
ClickTag.addEventListener(MouseEvent.CLICK, goToURL);

// Function to redirect the URL
function goToURL(Evt:MouseEvent) {
 // Set the URL Request variable
 var targetURL:URLRequest = new URLRequest(clickTAG);
 // Check if the url contain the http: section
 if (clickTAG.substr(0,5) == "http:") {
 // Navigate the URL
 navigateToURL(targetURL, "_blank");

 }
}

The Go Programming Language

Go is a systems programming language intended to be a general-purpose systems language, like C++. It is compiled, garbage-collected, concurrent programming language developed by Google. Go was officially announced in November 2009, with implementations released for the Linux and Mac OS X platforms. It is Simple, Fast. Safe, Concurrent, Fun and finaly it is Open source.

Go compilers produce fast code fast. Typical builds take a fraction of a second yet the resulting programs run nearly as quickly as comparable C or C++ code.

Go is type safe and memory safe. Go has pointers but no pointer arithmetic. For random access, use slices, which know their limits.

Go promotes writing systems and servers as sets of lightweight communicating processes, called goroutines, with strong support from the language. Run thousands of goroutines if you want—and say good-bye to stack overflows.

Go has fast builds, clean syntax, garbage collection, methods for any type, and run-time reflection. It feels like a dynamic language but has the speed and safety of a static language. It’s a joy to use.

Shell Commands

msgfmt -c -v -o out_message.mo input_message.po

# ############### Options are ###########
# -c option does detailed checking of the PO file format.
#
# -v makes the program verbose.
#
# -o option output filename.

http://www.gnu.org/software/gettext/
http://gnuwin32.sourceforge.net/packages/gettext.htm

Download the latest release from the link and extract to you machine. And execute the following commands.
Note: In my example, the package path is C:GnuWin32bin and the source file are int C:source_file Openup the Command Prompt and move to the bin folder.

Suppose my PHP source file contents are as like this:

PHP Source File

<?php
// file path: c:source_filetest.php
$my_name = "Midhun Devasia";
printf(gettext("This is a first text...by %s"), $my_name);
printf(gettext("This is a second text.!"));
?>

Extract all the strings from program source file:

Shell Commands

xgettext -o extract_out.pot test.php
#or(specify domain)
xgettext –d MyApp -o extract_out.pot test.php

-o Output file name is optional, by default it save as messages.po.
-d Domain optional, and should match the domain specified in the call to textdomain

So the above command fetch all the strings from the gettext() function.
So you will get the .po file contents as like this:

Sample PO file

#: c:/source_file/test.php:3
#, php-format
msgid "This is a first text...by %s"
msgstr ""

#: c:/source_file/test.php:4
#, php-format
msgid "This is a second text.!"
msgstr ""

PHP Template File

But if your are using a template files (like .phtml, ctp, etc..) , the format is something like this

// template file content
<?= $this->lang("another method for the string extraction");?>

Here you need to specify the extra argument to the xgettext function. ie - – keyword.

Shell Commands

xgettext –keyword=lang -o extract_out.pot test.php
