I'd like to return the first key value in the following array such that England would return 1 rather than 3 which is the second key value. Any help would be greatly appreciated. $c[1][]="Vietnam"; $c[1][]="China"; $c[1][]="Thailand"; $c[1][]="England"; $c[2][]="USA"; $c[2][]="Japan"; print_r($c); // Array ( [1] => Array ( [0] => Vietnam [1] => China [2] => Thailand [3] => England ) [2] => Array ( [0] => USA [1] => Japan ) ) foreach($c as $row) {

give this a shot <?php function findIndexof($ar, $str) { foreach($ar AS $k => $v) { if ( is_array($v) ) {

     $val = findIndexof($v, $str);
     if( $val !== false ) {
       return $val;
     }

} elseif ( strtolower($v) == strtolower($str) ) {

     return $k;

} } return FALSE; } $c[1][] = "Vietnam"; $c[1][] = "China"; $c[1][] = "Thailand"; $c[1][] = "England"; $c[2][] = "USA"; $c[2][] = "Japan"; echo findIndexof($c, 'Vietnam'); ?> You should be able to search arrays of any depth Hope this woks for you. Jim

Or, a lot easier: foreach($c as $key=>$row) { if(false !== array_search("England",$row)) {

    echo $key;

} }
