I often find myself doing quick checks like this:

if (! eregi('.php',$fileName))
      $filename.='.php';

But sadly eregi() is going to be deprecated in PHP 6, which means all of my code that uses it will be rendered useless :(.

Is there another function that behaves exactly the same way as eregi()? I don't know anything about reg exps and don't want to learn, so preg_match() etc won't work for me.
