Function to emulate the register_globals setting in PHP

While we all appreciate the many helpful posts to get rid of register_globals, maybe you're one of those who just loves it. More likely, your boss says you just have to live with it because he thinks it's a great feature.

No problem, just call (below defined):

<?php register_globals(); ?>

anywhere, as often as you want. Or update your scripts!

<?php
/**
* function to emulate the register_globals setting in PHP
* for all of those diehard fans of possibly harmful PHP settings :-)
* @author Ruquay K Calloway
* @param string $order order in which to register the globals, e.g. 'egpcs' for default
*/
function register_globals($order = 'egpcs')
{
    // define a subroutine
    if(!function_exists('register_global_array'))
    {
      function register_global_array(array $superglobal)
      {
      foreach($superglobal as $varname => $value)
      {
      global $$varname;
      $$varname = $value;
      }
      }
    }

    $order = explode("\r\n", trim(chunk_split($order, 1)));
    foreach($order as $k)
    {
      switch(strtolower($k))
      {
      case 'e': register_global_array($_ENV); break;
      case 'g': register_global_array($_GET); break;
      case 'p': register_global_array($_POST); break;
      case 'c': register_global_array($_COOKIE); break;
      case 's': register_global_array($_SERVER); break;
      }
    }
}
?>
