I have a large array of arrays and each of these sub-arrays has an ID and some other info. Is there a way to access an array of just the ID's without using a loop?
Sort of like
$array[ALLOFTHEITEMS][Id];
I want to eventually compare these ID's to another flat array of ID's. I would usually do a for loop and then just add the id of each item to a new array and then compare them. But is there a faster way?
