It means that you are trying to call a function from an variable that isn't an object -- EXACTLY what it states.

i.e.

[php]$pObj = NULL;
$pObj->free();[/php]

That will produce the same error because $pObj is not actually an object, even though it's variable name would make you think so.

There is no "free()" function. MySQL resources don't have any functions of their own at all.

Maybe you're after mysql_free_result().

Changed thread title to better describe the problem (did you know that threads whose titles contain phrases such as, 'please help' actually get FEWER responses?).
