PHP Bug Type: Arrays related
Bug description: foreach($_GET as $key => &$value) causes later bugs passing
$_GET as a paramete
Description:
------------
if we iterate over $_GET using references (see the example) and pass $_GET
to a function, function modifies $_GET and not the local copy.
For example, save the example code in test.php and open
test.php?mykey=foo
.
Reproduce code:
---------------
<?php
function doit($http_get_params)
{
$http_get_params['mykey'] = 'bar';
echo '<br/>'.$_GET['mykey'];
}
foreach($_GET as $key => &$value) {}
echo '<br/>'.$_GET['mykey'];
doit($_GET);
echo '<br/>'.$_GET['mykey'];
?>
Expected result:
----------------
When we open test.php?mykey=foo I expect to see
foo
foo
foo
Actual result:
--------------
When we open test.php?mykey=foo we actually see
foo
bar
bar
