Description:
------------
Script was working perfectly on PHP 4 when updated to PHP5.2.9 I found
an error. I was filling a array in the session and looped it with
array_shift until the arry was empty.
This loop kept giving me the first value but did not erased it from te
original arry.
Reproduce code:
---------------
$row = array_shift(@$_SESSION['villas']);
Expected result:
----------------
1. $row getting the first element from $_SESSION['villas']
2. $_SESSION['villas'] to get lost the first element.
Actual result:
--------------
1. $row getting the first element from $_SESSION['villas']
2. $_SESSION['villas'] did not lost the first element and was
unchanged
I cann bypass this failure by using:
$arr_temp = @$_SESSION['villas'];
$row = array_shift($arr_temp);
$_SESSION['villas'] = $arr_temp;
unset($arr_temp);
