Bug #43806 Unexpected result using 'foreach'
Submitted: 2008-01-10 11:25 UTC Modified: 2008-01-10 12:22 UTC
From: pepalegre at terra dot es Assigned:
Status: Not a bug Package: Arrays related
PHP Version: 5.2.5 OS: openSUSE 10.3
Private report: No CVE-ID: None
 [2008-01-10 11:25 UTC] pepalegre at terra dot es
Description:
------------
If I declare a reference variable (&$value) and use it in a 'foreach' and then I reuse it in the same loop like a normal variable ($value), I have an unexpected result, array is modified!
Note that using another variable in the second 'foreach' the result is Ok.


Reproduce code:
---------------
<?php
        $v = array (1,2,3);
        foreach($v as &$value);
        print_r($v);
        foreach($v as $value);
        print_r($v);
?>


Expected result:
----------------
Array
(
    [0] => 1
    [1] => 2
    [2] => 3
)
Array
(
    [0] => 1
    [1] => 2
    [2] => 3
)


Actual result:
--------------
Array
(
    [0] => 1
    [1] => 2
    [2] => 3
)
Array
(
    [0] => 1
    [1] => 2
    [2] => 2
)

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.
