Answer 1

You can use the index of first array to get to the second array the use index b to check the data.Try this:

$arr1 = array('a'=>'1');
$arr2 = array('a'=>'2');
$arr3 = array('a'=>'3');
$another_arr1 = array($arr1,$arr2,$arr3);
$arr4 = array('b'=>'4');
$arr5 = array('b'=>'5');
$arr6 = array('b'=>'6');
$another_arr2 = array($arr4,$arr5,$arr6);

foreach ($another_arr1 as $key=>$_another_arr1){
    foreach ($_another_arr1 as $another1){
    $another_arr2_value = (!empty($another_arr2[$key]['b']))? $another_arr2[$key]['b']:'';//check if value in second array exists 
    echo $another1.' ->'. $another_arr2_value."<br>";
    }

}
