note 117256 added to function.get-headers

Testing the validity of a URL that is preceded by one or more server redirects is tricky. There will be more than one status code returned and all but the first will be redirect codes. This function will return an integer containing the three digit status code of the last code returned, which is what you want. function getStatus($url) { $headers = @get_headers($url, true); foreach($headers as $k => $v) { if (! is_int($k)) continue; $value = $v; } return (int) substr($value, strpos($value,' ', 8) +1, 3); } ---- Server IP: 72.52.91.14 Probable Submitter: 70.197.195.4 ---- Manual Page -- http://php.net/manual/en/function.get-headers.php Edit -- https://master.php.net/note/edit/117256 Del: integrated -- https://master.php.net/note/delete/117256/integrated Del: useless -- https://master.php.net/note/delete/117256/useless Del: bad code -- https://master.php.net/note/delete/117256/bad+code Del: spam -- https://master.php.net/note/delete/117256/spam Del: non-english -- https://master.php.net/note/delete/117256/non-english Del: in docs -- https://master.php.net/note/delete/117256/in+docs Del: other reasons-- https://master.php.net/note/delete/117256 Reject -- https://master.php.net/note/reject/117256 Search -- https://master.php.net/manage/user-notes.php
