note 57797 added to function.array-count-values

alwaysdrunk's comment only works if you can trust the client web browser. Using this function doesn't validate that every necessary field exists -- only that every field that was submitted has a value in it. Thus if an attacker wished to force a null value into one of the fields, he could (rather easily) construct a modified form without the field and submit THAT. Besides, you really ought to be validating each field anyway if you're taking user input. ---- Manual Page -- http://www.php.net/manual/en/function.array-count-values.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+57797 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+57797&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+57797&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+57797&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+57797&report=yes&reason=useless Delete: non-english -- http://master.php.net/manage/user-notes.php?action=delete+57797&report=yes&reason=non-english Delete: already in docs -- http://master.php.net/manage/user-notes.php?action=delete+57797&report=yes&reason=already+in+docs Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+57797&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+57797&report=yes Search -- http://master.php.net/manage/user-notes.php
