I have to change a javascript function into php function, which convert unicode data. it's ok for changing simple replace function into php preg_replace e.g.

JavaScript

var output = str.replace(/\u104E\u1004\u103A\u1038/g, '\u104E');

into

PHP

$output = preg_replace('/\u104E\u1004\u103A\u1038/g', '\u104E',$str);

My problem is that how to convert following javascript replace function with inline function. e.g.

JavaScript

output = str.replace(/([\u103B\u103C][\u103D]?[\u103E]?[\u102D\u1036]?)\u1030/g, function($0, $1)
   {
      return $1 ? $1 + '\u1034' : $0 + $1;
   }
   );

I have no idea how inline function works and how to implement it in php. Please help me how to solve this problem.

But why you want to convert same function in PHP because from the PHP you can use javascript.

sure, but I want to get output as string to implement as server side method instead of directly displaying result and output buffering cannot be used for this purpose as output buffer will produce javascript code.<br><br>
There are some other techniques such as pecl v8js php extension to invoke javascript function directly on server side, but I don't want to use this way for such string manipulation purpose.

My problem is that I don't know how to implement second parameter inline function in php
function($0, $1)
{
return $1 ? $1 + '\u1034' : $0 + $1;
}
I want to know how to get regex-matches from pattern

This script is to reorder unicode character order and this is myanmar unicode which is still under development. so as for me it's hard to say input. therefore let me show sample with westen text as follow:
output = str.replace(/([ab][c]?[d]?[ac]?)some/g, function($0, $1)
{
return $1 ? $1 + 'changed' : $0 + $1;
}
);
I'm not sure this can cover original problem, Thanks alot.
