note 57313 added to function.in-array

Beware of a bug in PHP 4.3.4 (and possibly other versions): in_array('some_string', array(0)) returns true! If the array contains the element 0, any string you search will return 0. ---- Manual Page -- http://www.php.net/manual/en/function.in-array.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+57313 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+57313&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+57313&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+57313&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+57313&report=yes&reason=useless Delete: non-english -- http://master.php.net/manage/user-notes.php?action=delete+57313&report=yes&reason=non-english Delete: already in docs -- http://master.php.net/manage/user-notes.php?action=delete+57313&report=yes&reason=already+in+docs Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+57313&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+57313&report=yes Search -- http://master.php.net/manage/user-notes.php
