I avoid using (require|include)_once and instead, use constant define at the top of my php files to avoid redefining classes/functions.
At the top of a file I will have (say query.php):
<?php
global $query; // Shared global reference
if (defined('_QUERY_PHP_')) {
return; // return and do no more processing
}
define('_QUERY_PHP_', 1);
class query {
... rest of file with class/functions
}
$query = new query;
?>
When I have eaccelerator off, it works as expected. When I turn it on, I get
Fatal error: Cannot redeclare class query in [snipped]/query.php on line 0
