You're using a lot of negatives.

nice catch on the double neg Rory :-)

$data = array(); // You should initialise $data to array() for various reasons: // 1: self_documentation - to anyone who reads your code will be obvious

//     that $data should contain an empty array
// 2: security - if someone goes to //  http://yoursite.com/page.php?data[]=something_bad_here and you have //  register_globals on(which should be, but not assumed to be, off)

is it always necessary to call array() when you do something like this: mysql_query("SELECT ...."); while($rows .....) { $data[] = $rows; } if so, why? i have a habit of never calling array() and someone told me i shouldn't do this.

Someone told you you shouldn't not call array() - in other words you should call array(). If I'm reading you correctly then the someone is right. You should not use a variable without initialising it, unless it comes from a form, in which case you should not use it without "cleaning" it.
