The faulty code is below.

This is a VERY bad bug. It will cause Apache / PHP to eat CPU cycles and put in the log the following line continuously:<br>
Fatal error  ht=40310d44 is already destroyed in zend_hash.c:519 in Unknown on line 0<br>

This is not a dir() bug. It happens any time you try to store a resource object (such as dir(), mysql_query(), etc.) in a static variable.<br><br>

&lt;?
static $t = 0;
$t = dir(".");
