Question

Is there a better way to do the following:

$array = array('test1', 'test2', 'test3', 'test4', 'test5'); // do a bunch of other stuff, probably a loop $array[] = 'test6'; end($array); echo key($array); // gives me 6 

This will give the key of the most recently add array element.

Is there a better way to do this?

Answer 1

You could also do:

$end = end(array_keys($array)); 

But I think your way makes it clear what you want to do, so you could whip something up like:

function array_last_key($array) {     end($array);     return key($array); } 

That’s about it.
