More over.. PHP seems to be quiet slow when dealing with array_shift()
array_unshift(), but it is much faster with array_pop() array_push(). I
am not familiar with the PHP internals, but why not add a pointer to the
start and end of the array?
Good word can be said on PHP that accelerated at least count() function..
Maybe I require too much.. PHP is a rapid development scripting
language.. not a massive optimized programming language.. :-/

Hi,
Why isn't there a function that acts like array_pop() returns a pair of
key-value rather than the value only ?
Reason is, that in order to pop the key-value pair, you do:
<?php
$arr = array('a'=>1,'b'=>2,'c'=>3,'d'=>4);
$arr_keys = array_keys($arr);
$key = array_pop($arr_keys);
$value = $arr[$key];
?>
I benchmarked array_keys() function and it is very slow on big arrays
since PHP has to build the array. While array_pop() can be acceleraed by
the guts of PHP engine.
