Tried that already. It didn't maintain the order of the fruit name but did do the numeric correctly

Seems there was a typo on that function, see this revision:

I think you may want this.  The man page for asort refers to the man page for sort for the sort flags.

HTH, ~Ray
<?php 
 
$sorted_array = asort($array, 'SORT_NUMERIC');
