note 53926 added to types.comparisons

<?php if (strlen($_POST['var']) > 0) { // form value is ok } ?> When working with HTML forms this a good way to: (A) let "0" post values through like select or radio values that correspond to array keys or checkbox booleans that would return FALSE with empty(), and; (B) screen out $x = "" values, that would return TRUE with isset()! Because HTML forms post values as strings, this is a good way to test variables! ---- Manual Page -- http://www.php.net/manual/en/types.comparisons.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+53926 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+53926&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+53926&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+53926&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+53926&report=yes&reason=useless Delete: non-english -- http://master.php.net/manage/user-notes.php?action=delete+53926&report=yes&reason=non-english Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+53926&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+53926&report=yes Search -- http://master.php.net/manage/user-notes.php
