This isn't a support question, I'm not asking for help in a script.
It's a minor bug in the way the script is parsed when nesting
functions.
The code in which I discovered the bug used explode() inside
array_pop(), I only used my example code to simplyfy things.
array_pop() is returning the last element of the array but isn't
truncating the array inside it. As I say, things work as expected in
PHP4 so why would PHP5 return the last element of the array without
truncating it?

Sorry, but your problem does not imply a bug in PHP itself. For a
list of more appropriate places to ask for help using PHP, please
visit http://www.php.net/support.php as this bug system is not the
appropriate forum for asking support questions. Due to the volume
of reports we can not explain in detail here why your report is not
a bug. The support channels will be able to provide an explanation
for you.
Thank you for your interest in PHP.

Description:
If you create an array inside array_pop(), expecting that array to be
popped then it isn't even though the last element of that array is
returned as expected.
Creating the array on the previous line makes array_pop() behave as
expected.
This behaviour doesn't occur in PHP4.3.x on FreeBSD. I only noticed it
when I upgraded to PHP 5.1.2 on my home WinXP machine though it's
possible it was broken but I didn't notice it in 5.0.x
Reproduce code:
---
$a=array(0, 1, 2, 3, 4, 5); // Set array first.
$offcut=array_pop($a); // Then pop array.
$length=count($a);
echopreArray offcut:
.$offcut.\nArray length:
.$length.\nLast element:
.$a[$length-1]./pre\n;
$offcut=array_pop($a=array(0, 1, 2, 3, 4, 5)); // Set and pop at the
same time.
$length=count($a);
echopreArray offcut:
.$offcut.\nArray length:
.$length.\nLast element:
.$a[$length-1]./pre\n;
Expected result:
Array offcut: 5
Array length: 5
Last element: 4
Array offcut: 5
Array length: 5
Last element: 4
Actual result:
--
Array offcut: 5
Array length: 5
Last element: 4
Array offcut: 5
Array length: 6
Last element: 5
