Operating system: Linux 2.4.21-99
PHP version: 5.1.0RC1
PHP Bug Type: Scripting Engine problem
Bug description: Different code execution order than in previous PHP versions
Description:
------------
I noticed a slight change in the order some instructions
get executed.
The execution order of instructions for a code like
$result[$base]=$base++;
differs from PHP 5.1 to previous versions so that the
$result variable also has different values as follows:
PHP 4.3.10 : array(1) { [0]=> int(0) }
PHP 5.0.3 : array(1) { [0]=> int(0) }
PHP 5.1.0b3 : array(1) { [1]=> int(0) }
PHP 5.1.0RC1 : array(1) { [1]=> int(0) }
Reproduce code:
---------------
$base=0;
$result[$base]=$base++;
var_dump($result);
Expected result:
----------------
To keep compatibility with PHP 4.x and 5.0.x:
array(1) { [0]=> int(0) }
Actual result:
--------------
array(1) { [1]=> int(0) }
