note 117291 added to function.get-headers

Correction to my earlier note on getting the last code returned as an int: if getHeaders() fails, PHP will throw an error. Here's the corrected function: function getStatus($url) { $headers = @get_headers($url, true); $value = NULL; if ($headers === false) { return $headers; } foreach ($headers as $k => $v) { if (!is_int($k)) { continue; } $value = $v; } return (int) substr($value, strpos($value, ' ', 8) + 1, 3); } Test the return value for === false. ---- 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/117291 Del: integrated -- https://master.php.net/note/delete/117291/integrated Del: useless -- https://master.php.net/note/delete/117291/useless Del: bad code -- https://master.php.net/note/delete/117291/bad+code Del: spam -- https://master.php.net/note/delete/117291/spam Del: non-english -- https://master.php.net/note/delete/117291/non-english Del: in docs -- https://master.php.net/note/delete/117291/in+docs Del: other reasons-- https://master.php.net/note/delete/117291 Reject -- https://master.php.net/note/reject/117291 Search -- https://master.php.net/manage/user-notes.php
