note 117419 added to function.in-array

if using in_array to evaluate a boolean in a _GET or _POST, be sure to put single quotes around your "haystack values" or you will get a false result. example of false/incorrect result: [whatever.php?var=1 -- $_GET['var'] is 1] if(!in_array($_GET['var'], array(0, 1), true)){ echo 'not in array'; } else{ echo 'is in array'; } output is "not in array" even though 1 === 1. Same is true without strict evaluation. example of correct evaluation/result: [whatever.php?var=1 -- $_GET['var'] is 1] if(!in_array($_GET['var'], array('0', '1'), true)){ echo 'not in array'; } else{ echo 'is in array'; } output is now correct; "is in array". ---- Server IP: 72.52.91.14 Probable Submitter: 98.251.242.46 ---- Manual Page -- http://php.net/manual/en/function.in-array.php Edit -- https://master.php.net/note/edit/117419 Del: integrated -- https://master.php.net/note/delete/117419/integrated Del: useless -- https://master.php.net/note/delete/117419/useless Del: bad code -- https://master.php.net/note/delete/117419/bad+code Del: spam -- https://master.php.net/note/delete/117419/spam Del: non-english -- https://master.php.net/note/delete/117419/non-english Del: in docs -- https://master.php.net/note/delete/117419/in+docs Del: other reasons-- https://master.php.net/note/delete/117419 Reject -- https://master.php.net/note/reject/117419 Search -- https://master.php.net/manage/user-notes.php
