php - Compare two multidimensional Associative arrays -


i've been trying hours now. have 2 multidimensional arrays.

$newdata ( [0] => array(     [id] => 1     [name] => john     [sex] => male ) [1] => array(     [id] => 2     [name] => kenny     [sex] => male ) [2] => array(     [id] => 3     [name] => sarah     [sex] => female ) [3] => array(     [id] => 4     [name] => george     [sex] => male ) )  $olddata ( [0] => array(     [id] => 3     [name] => sarah     [sex] => female ) [1] => array(     [id] => 4     [name] => george     [sex] => male ) [2] => array(     [id] => 5     [name] => peter     [sex] => male ) [3] => array(     [id] => 6     [name] => lexi     [sex] => female ) )

if name in $olddata matched $newdata need fetch id of array without using more loops

you want use array_search()

which can return key of array find match in.

eg

$key = array_search('$array1['name']', $array2);
