Jochem,
Whoa... what do you mean by this, exactly? I am running PHP 5.0.4 and
$var is correctly set with the code you give above. I could not find
anything like you describe in the array_pop manual (see below).
Please elaborate on why this is "bad" code.

array_pop
(PHP 4, PHP 5)
array_pop -- Pop the element off the end of array
Description
mixed array_pop ( array &array )
array_pop() pops and returns the last value of the array, shortening
the array by one element. If array is empty (or is not an array),
NULL will be returned.
Note: This function will reset() the array pointer after use.
Example 1. array_pop() example
<?php
$stack = array("orange", "banana", "apple", "raspberry");
$fruit = array_pop($stack);
print_r($stack);
?>
After this, $stack will have only 3 elements:
Array
(
[0] => orange
[1] => banana
[2] => apple
)
and raspberry will be assigned to $fruit.
See also array_push(), array_shift(), and array_unshift().
