my array looks this:

$arr = array(); $arr[] = array("foo", "bar"); $arr[] = array("test", "hello"); 

now want check if $arrcontains array contains foo on first position.

is there function or should loop $arr , search through every array inside it?

one nifty little way of doing use array_reduce – passing in function sums values 1 if foo found, , 0 if not:

$foo_found = array_reduce(   $arr,   function ($num_of_hits, $item, $search_for = 'foo') {     $num_of_hits += $item[0] === $search_for ? 1 : 0;     return $num_of_hits;   } );  $xyz_found = array_reduce(   $arr,   function ($num_of_hits, $item, $search_for = 'xyz') {     $num_of_hits += $item[0] === $search_for ? 1 : 0;     return $num_of_hits;   } );  var_dump($foo_found, $xyz_found); 

returns 1 , 0, cause foo found once, , xyz found 0 times.
