Description:
------------
According to the operator precedence
(http://www.php.net/manual/en/language.operators.php#language.operators.precedence),
a (post)increment should be evalued after the '['.
It seems that isn't true in assigning to an array in PHP5 anymore,
while it was in PHP4. Latest snapshots of both checked (30-07-2007).
This could also be a documentation problem.
Reproduce code:
---------------
<?php
$k = 1;
$a = array();
$a[$k] = $k++;
var_dump($a,$k);
?>
Expected result:
----------------
array(1) {
[1]=>
int(1)
}
int(2)
Actual result:
--------------
array(1) {
[2]=>
int(1)
}
int(2)
