Answer 1

Simple way to find the max value from two dimensional array is using foreach statement, convert the key field from which we need to find the max value to another single dimensional array and get max value using 'max' function as below

$recCountArray = array();
foreach ($devices as $device) {
   $recCountArray[] = $availableDevice['recCount'];
}

$maxCount = max($recCountArray);
