find highest numerical index of an array

[pakenney38]

Assume that the first numerical index of a given array is 0. Is there any way to find the highest numerical index of the array? I want to avoid using something like, if I can:

$highest_index = count($array) - 1;

<?php

   krsort($array); //Sort your array in reverse order by key.
   $highest = key($array); //Get array's current key
   ksort($array); //Back to normal.

?>

 

Or....

 

<?php

   end($array);
   $highkey = key($array);
   next($array);

?>

 

I suppose array_keys isn't much help since it just returns another array with keys. We can get those from the original array anyway. It is possible there's a much better way...but it's early and I haven't had my corporate fave Starbucks yet.

Hmm, count will give you a count of the elements which may return a number which is not likely to be the highest index number because 1.) Index's can be unset, 2.) Index's might not be numerical

 

If you need the value of the last element you could use the end() function.

Thanks. That will work. I had done that once before and forgot I could do it that way.
