But if i want to execute a specific function inside

Answer 1

You will have to expose it in some way. This is because exposing all methods public, would be a security risk.

Example.php

<?php

    function CalculateLength($source)
    {
        return strlen($source);
    }

    if(isset($_GET['calculate-length']) && isset($_GET['value']){
        die(CalculateLength($_GET['value']));
    }

?>

Then just call:

http://www.example.com/Example.php?calculate-length&value=My%20example

Answer 2

 if (isset($GET[param_name])){

  if($GET[param_name] === value)
   {
      function 1... 
    } else if 
 {

function 2...
 }

}
