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 ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=39011&edit=1
