[Phpwm] Accessing class variable from sub function

[Mike Tipping]

This is probably a silly question but I can't work it out.

I'm using preg_replace_callback which takes a callback function as a
parameter. The call to preg_replace_callback is within a class and I need
the callback function to have access to the classes properties, but can't
work out how to give it access.

So with something like this:

Class myclass {

  public someData = array();
  
  function replaceText($someText) {
    function callbackFunc($matches) {
      print_r(xxx);
    }    
    reg_replace_callback('/{id="1"}/' ," callbackFunc", $fileContent);
  }  

}

What do I need to replace xxx with to access the array someData?

Or am I approaching this in completely the wrong way?

Cheers

Mike
