Make module_builder 5,x work in PHP4

feedback:

under php 4.4.2-1.1 (debian stable), the module fatals on pressing "download module"
Fatal error: Call to undefined function: stripos() in /home/brenda/projects/drupal/contributions/modules/module_builder/module_builder.module on line 286

i'm not sure of drupal policy for support of php4, but until debian stable moves i must stick with php4.
I've attached a patch that adds the following:

<?php
//Helper function, for php4
if (!function_exists('stripos')) {
	function stripos($string,$word){
		$retval = false;
		for($i=0;$i<=strlen($string);$i++) {
			if (strtolower(substr($string,$i,strlen($word))) == strtolower($word)) {
				$retval = true;
			}
		}
		return $retval;
	}
}
?>

* Fieldsets in Opera look mondo bizarr-o

I tested in Opera (9.02-20060919.6) on ubuntu amd64 - display pretty much the same as in firefox (2.0.0.2+0dfsg-0ubuntu0.6.10).

Wouldn't this be quicker:

if (!function_exists("stripos")) {
  function stripos($str, $needle, $offset=0)
  {
      return strpos(strtolower($str), strtolower($needle), $offset);
  }
}

What's the status on this?

The development snapshot is now out, hoping to see some issues pop up. Changing the title to having to do with PHP4, as it seems this is what's being discussed here.

Closing this as surely now everyone has PHP5 at least on their development system.
