note 99973 added to function.parse-url

For those of you sending URLs in HTML emails with a redirect address in the query string, note that Hotmail unescapes / and : characters in the query string. So that breaks the parse_url() function call. Take this as an example: href="http://example.com/redirect?url=http%3A%2F%2Fplanio.com" Hotmail will transform it to this: href="http://example.com/redirect?url=http://planio.com" The solution is to be preventive before the call to parse_url(): <?php $q_index = strpos($uri, '?'); if ($q_index !== FALSE && (strpos($uri, ':', $q_index) !== FALSE || strpos($uri, '/', $q_index) !== FALSE)) { $begin = substr($uri, 0, $q_index); $end = substr($uri, $q_index, strlen($uri)-$q_index); $end = str_replace('/', '%2F', $end); $end = str_replace(':', '%3A', $end); $uri = $begin.$end; } ?> ---- Server IP: 216.235.13.26 Probable Submitter: 69.70.138.86 ---- Manual Page -- http://www.php.net/manual/en/function.parse-url.php Edit -- https://master.php.net/note/edit/99973 Del: integrated -- https://master.php.net/note/delete/99973/integrated Del: useless -- https://master.php.net/note/delete/99973/useless Del: bad code -- https://master.php.net/note/delete/99973/bad+code Del: spam -- https://master.php.net/note/delete/99973/spam Del: non-english -- https://master.php.net/note/delete/99973/non-english Del: in docs -- https://master.php.net/note/delete/99973/in+docs Del: other reasons-- https://master.php.net/note/delete/99973 Reject -- https://master.php.net/note/reject/99973 Search -- https://master.php.net/manage/user-notes.php
