For a list of more appropriate places to ask for help using PHP, please visit http://www.php.net/support.php as this bug system is not the appropriate forum for asking support questions. Due to the volume of reports we can not explain in detail here why your report is not a bug. The support channels will be able to provide an explanation for you. Thank you for your interest in PHP. You cannot use arrays or objects as keys. Doing so will result in a warning: Illegal offset type. Check your code. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
