If you make typo on registerfunction (w32api), it will completly screw php.
Following line made mine Apache to crash and I can't get start it anymore if I don't remove php module. CGI version is screwed too.
<?php
$api = new win32;
$api->registerfunction("long SendMessage (string &a, string &b, int &c, sring &d) From user32.dll");
?>
(note that there isn't t at last argument).
