php - check associative array contains value -

    array (         [0] => array (                 [questionid] => 47                [surveyid] => 51                [userid] => 31                 [question_title] => choose one?                 [question_type] => dropdown                 [response] => 1.android 2.windows 3.blackberry                 [required] => 0                 [add_time] => 0     )     [1] => array (                 [questionid] => 48                 [surveyid] => 51                 [userid] => 31                 [question_title] => it?                 [question_type] => bigbox                 [response] => yes no                 [required] => 1                 [add_time] => 0      )         [2] => array (                 [questionid] => 129                 [surveyid] => 51                 [userid] => 31                 [question_title] => select                 [question_type] => single                 [response] => dfg hbk ghck hk                 [required] => 0                 [add_time] => 0      ) )  

this multidimensional

now want check array contains [required] => 1 or [required] => 0

i don't want traversing array

let's array name $myarray

so can -

foreach($myarray $arrelement) {     if(isset($arrelement[required]) && $arrelement[required] == 1) //choose 1 or 0 in code per need     {          //traverse array , needful     } }
