note 86413 added to function.parse-url

Some example that determines the URL port. When port not specified, it derives it from the scheme. <?php function getUrlPort( $urlInfo ) { if( isset($urlInfo['port']) ) { $port = $urlInfo['port']; } else { // no port specified; get default port if (isset($urlInfo['scheme']) ) { switch( $urlInfo['scheme'] ) { case 'http': $port = 80; // default for http break; case 'https': $port = 443; // default for https break; case 'ftp': $port = 21; // default for ftp break; case 'ftps': $port = 990; // default for ftps break; default: $port = 0; // error; unsupported scheme break; } } else { $port = 0; // error; unknown scheme } } return $port; } $url = "http://nl3.php.net/manual/en/function.parse-url.php"; $urlInfo = parse_url( $url ); $urlPort = getUrlPort( $urlInfo ); if( $urlPort !== 0 ) { print 'Found URL port: '.$urlPort; } else { print 'ERROR: Could not find port at URL: '.$url; } ---- Server IP: 83.137.20.135 Probable Submitter: 212.238.158.23 ---- Manual Page -- http://www.php.net/manual/en/function.parse-url.php Edit -- https://master.php.net/note/edit/86413 Del: integrated -- https://master.php.net/note/delete/86413/integrated Del: useless -- https://master.php.net/note/delete/86413/useless Del: bad code -- https://master.php.net/note/delete/86413/bad+code Del: spam -- https://master.php.net/note/delete/86413/spam Del: non-english -- https://master.php.net/note/delete/86413/non-english Del: in docs -- https://master.php.net/note/delete/86413/in+docs Del: other reasons-- https://master.php.net/note/delete/86413 Reject -- https://master.php.net/note/reject/86413 Search -- https://master.php.net/manage/user-notes.php
