note 16273 added to function.array-multisort

Sorry - am I mad? I have tried repeatedly to use this function, but all I get is a complaint that the first arg I supply must be an array - which it clearly is (even doing a var dump reveals that somewhere PHP considers it to be an array). Under what circumstances would it not appear to be an array to the function ...? -- http://www.php.net/manual/en/function.array-multisort.php http://master.php.net/manage/user-notes.php?action=edit+16273 http://master.php.net/manage/user-notes.php?action=delete+16273 http://master.php.net/manage/user-notes.php?action=reject+16273
