note 69712 added to function.in-array

in_array does not work for this case: If all items of an array as elements (not as an array) are in another array. For example: $arr1 = array("aaa", "bbb", "ccc", "ddd"); $arr2 = array("aaa", "bbb"); The following function is a solution to work it out: <? function arrElement_in_array($arr2, $arr1){ foreach($arr2 as $v){ if(in_array($v, $arr1)){ $count++; } } //if all elements of arr2 are in arr1 if($count==count($arr2)){ return true; } } ?> ---- Server IP: 216.194.113.175 Probable Submitter: 68.67.55.50 ---- Manual Page -- http://www.php.net/manual/en/function.in-array.php Edit -- https://master.php.net/note/edit/69712 Del: integrated -- https://master.php.net/note/delete/69712/integrated Del: useless -- https://master.php.net/note/delete/69712/useless Del: bad code -- https://master.php.net/note/delete/69712/bad+code Del: spam -- https://master.php.net/note/delete/69712/spam Del: non-english -- https://master.php.net/note/delete/69712/non-english Del: in docs -- https://master.php.net/note/delete/69712/in+docs Del: other reasons-- https://master.php.net/note/delete/69712 Reject -- https://master.php.net/note/reject/69712 Search -- https://master.php.net/manage/user-notes.php
