Description:
------------
When I order an array with the asort() function, the words that begin with an uppercase letter are ordered before the others.
I think a a case-insensitive would be useful. In fact, in the alphabet there isn't any difference between "A" and "a".
Example:
<?php
$array = array("cat", "Dog", "Mice");
asort($array);
print_r($array);
?>
This returns:

Array
(
    [1] => Dog
    [2] => Mice
    [0] => cat
)

It must return, instead

Array
(
    [0] => cat
    [1] => Dog
    [2] => Mice
)

because "cat" < "Dog" < "Mice".
