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;
