Errors Won't Show Up Even With Error_reporting(E_ALL) And Ini_set("display_errors","1")

Here's my code:

<?php

error_reporting(E_ALL);
ini_set("display_startup_errors","1");
ini_set("display_errors","1");

wefw
wefwef=wefwe
2349023909()
;wrgwrg ====232

phpinfo(); ?>

I get a blank page.

If I take out the crap, it prints phpinfo() just fine.

PHP 4.3.something...
