Get key of the last element in an array

Question

Hay, i have an array which contains a set of arrays, here's an example.

array(
    [0]=>array('name'=>'bob'),
    [2]=>array('name'=>'tom'),
    [3]=array('name'=>'mark')
)

How would i get the last item in the array, and returns it's key.

So in the above example it would return 3.

@yes123 this won't work if the keys are numerical and in exact order, without any missing. — Dunhamzzz

end($array);
echo key($array)

This should return the key of the last element.

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

@yes123 And? It still works, and it's all in one line which is nice.

<?php
$a = array(
    0=>array('name'=>'bob'),
    2=>array('name'=>'tom'),
    3=>array('name'=>'mark')
);


$b = array_keys($a);
echo end($b);

?>

something like this

Another option:

$last_key = key(array_slice($array, -1, true));

This won't preserve keys, which is probably a requirement here.

You can create function and use it:

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

$array = array("one" => "apple", "two" => "orange", "three" => "pear");
echo endKey($array);
