Some E_STRICT errors seem to be thrown during the page's compilation process. This means they cannot be disabled by dynamically altering the error level at run time within that page.
The work-around for this was to rename the file and replace the original with a error_reporting() call and then a require() call.
Ex, rename index.php to index.inc.php, then re-create index.php as:
<?php
error_reporting(E_ALL & ~(E_STRICT|E_NOTICE));
require('index.inc.php');
?>
That allows you to alter the error reporting prior to the file being compiled.
I discovered this recently when I was given code from another development firm that triggered several E_STRICT errors and I wanted to disable E_STRICT on a per-page basis.
