Original script is from http://www.jezra.net/blog/proof_of_concept_webserver_written_in_PHP
Modified for working with PFA by Aryes
Needs to find out how to send GET variables to the script
Until you must place some additional code similar to this to the
beginning of all your scripts:
$_a=$_SERVER['argv'][1];
if($_a){
  $_args_n_vars=explode("&",$_a);
  foreach($_args_n_vars as $_arg_n_var){
    list($_var,$_value)=explode("=",$_arg_n_var);
    $_GET[$_var]=urldecode($_value);
  }
}

After you can access all of $_GET variables sent from browser.
