As I read though how to get the last value of multidimensional array, end(array) has come up multiples times. My problem is similar, I have an array like this:

array = ( [12] => Array (xxx => xxx), [34] => Array (xxx => xxx), [56] => Array (yyy => yyy) );

I want to get the index number. If I use end(array) I will get the whole array indexed from [56]. How do I get [56] itself instead of the array?

P.S. I know I can use loop to get the last index number, I just don't want to loop though the whole array to just get the last index number...

$keys = array_keys($yourArray); $lastKey = $keys[count($keys)-1];

So, get the keys and pick the last one, does this suit you?

I wouldn't recommend this on very large arrays though, if you are doing an iterative operation. I believe the array_keys actually loops the array internally (confirm me on this please).

Alternatively, as @Ghost mentioned in a comment, you can point the array to end with end() and use key() on it to get the key (this is more performant):

end($yourArray); $lastKey = key($yourArray);

yeah just move the pointer to the end then use key
This is perfect! Thanks both of you :), so the process is simply moving the internal pointer to the end of an array and use key to get the index.
