note 115820 added to function.in-array

To identify all instances of $needle when both $needle and $haystack are arrays, combine in_array() with a loop through the array of needles. I've posted a functional example of it here: http://sandbox.onlinephpfunctions.com/code/930385800c30595129cefb87cfa7eec9d69dce08 $needles = array('John', 'Alex'); $haystack = array('John','Alexander','Kim', 'Michael'); foreach ($needles as $needle) { // Displays var name & value currently searching for) echo '$needle: '.$needle; if (in_array($needle, $haystack) ) { echo ', True; '; } else { echo ', False; '; } } Result is: $needle: John, True; $needle: Alex, False; ---- Server IP: 72.52.91.14 Probable Submitter: 108.41.27.161 ---- Manual Page -- http://php.net/manual/en/function.in-array.php Edit -- https://master.php.net/note/edit/115820 Del: integrated -- https://master.php.net/note/delete/115820/integrated Del: useless -- https://master.php.net/note/delete/115820/useless Del: bad code -- https://master.php.net/note/delete/115820/bad+code Del: spam -- https://master.php.net/note/delete/115820/spam Del: non-english -- https://master.php.net/note/delete/115820/non-english Del: in docs -- https://master.php.net/note/delete/115820/in+docs Del: other reasons-- https://master.php.net/note/delete/115820 Reject -- https://master.php.net/note/reject/115820 Search -- https://master.php.net/manage/user-notes.php
