You're using a lot of negatives. $data = array(); // You should initialise $data to array() for various reasons: // 1: self_documentation - to anyone who reads your code will be obvious // that $data should contain an empty array // 2: security - if someone goes to // http://yoursite.com/page.php?data[]=something_bad_here and you have // register_globals on(which should be, but not assumed to be, off) On 8/1/05, Sebastian <sebastian@xxxxxxxxxxxxxxxxxxx> wrote: > is it always necessary to call array() when you do something like this: > > mysql_query("SELECT ...."); > while($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. > > > -- > No virus found in this outgoing message. > Checked by AVG Anti-Virus. > Version: 7.0.338 / Virus Database: 267.9.7/60 - Release Date: 7/28/2005 > > -- > PHP General Mailing List (http://www.php.net/) > To unsubscribe, visit: http://www.php.net/unsub.php > > -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
