How to get index of array of object without using loop in PHP

Question

I need to get index of from array of objects without using loop as per the key name using PHP. Here I am explaining my code below.

$arr = array(array("name"=>"Jack","ID"=>10),array("name"=>"Jam","ID"=>11),array("name"=>"Joy","ID"=>12));
$key = array_search('Jack', $arr);

echo $key;exit;

Here my code does not give any output. By using some key name I need the index of that object present inside array and also I dont want to use any loop. I need Is ther any PHP in build method so that I can get the result directly.

<?php
$arr = array(array("name"=>"Jack","ID"=>10),array("name"=>"Jam","ID"=>11),array("name"=>"Joy","ID"=>12));

//calling function searchByName
$key = searchByName('Jasck',$arr);

if($key != '-1'){
  print_r($arr[$key]);  
}else{
    echo "No match found";
}

//function to chek if the name is there or not.
function searchByName($name, $array) {
   foreach ($array as $key => $val) {
       if ($val['name'] == $name) {
           return $key;
       }
   }
   return '-1';
}
