note 86621 added to function.fsockopen

When you're connecting through a proxy server you can't rely on fsockopen returning false to indicate that the connection has failed. (This also applies to fgets and fwrite.) To check whether the proxy succeeded in contacting the real target host, you need to look for the http response code in the headers that get returned. Typically, if the proxy was unable to reach the host, you'll find a line containing something like: HTTP/1.0 503 Service Unavailable ---- Server IP: 195.221.21.36 Probable Submitter: 129.184.84.11 ---- Manual Page -- http://www.php.net/manual/en/function.fsockopen.php Edit -- https://master.php.net/note/edit/86621 Del: integrated -- https://master.php.net/note/delete/86621/integrated Del: useless -- https://master.php.net/note/delete/86621/useless Del: bad code -- https://master.php.net/note/delete/86621/bad+code Del: spam -- https://master.php.net/note/delete/86621/spam Del: non-english -- https://master.php.net/note/delete/86621/non-english Del: in docs -- https://master.php.net/note/delete/86621/in+docs Del: other reasons-- https://master.php.net/note/delete/86621 Reject -- https://master.php.net/note/reject/86621 Search -- https://master.php.net/manage/user-notes.php
