Deprecated function ereg() and ereg_replace() errors breaking plugin

I’m running PHP 5.3 on my hosting account and these nasty DEPRECATED errors are showing, causing the plugin to not work:

Deprecated: Function ereg() is deprecated in /html/conway/wp-content/plugins/portable-phpmyadmin/wp-pma-mod/libraries/check_user_privileges.lib.php on line 59

Deprecated: Function ereg_replace() is deprecated in /html/conway/wp-content/plugins/portable-phpmyadmin/wp-pma-mod/libraries/check_user_privileges.lib.php on line 62

Thanks for the awesome plug-in by the way! Very helpful.
