PHP getting full server name including port number and protocol

Question

In PHP, is there a reliable and good way of getting these things:

Protocol: i.e. http or https Servername: e.g. localhost Portnumber: e.g. 8080

Answer 1

$protocol = isset($_SERVER['HTTPS']) && (strcasecmp('off', $_SERVER['HTTPS']) !== 0);
$hostname = $_SERVER['SERVER_ADDR'];
$port = $_SERVER['SERVER_PORT'];

Answer 2

Why don't you get full url like this

strtolower(array_shift(explode("/",$_SERVER['SERVER_PROTOCOL'])))."://".$_SERVER['SERVER_NAME'];

or (If you want host name from HTTP)

strtolower(array_shift(explode("/",$_SERVER['SERVER_PROTOCOL'])))."://".$_SERVER['HTTP_HOST'];

Answer 3

Compiled from above:

function getMyUrl()
{
  $protocol = (!empty($_SERVER['HTTPS']) && (strtolower($_SERVER['HTTPS']) == 'on' || $_SERVER['HTTPS'] == '1')) ? 'https://' : 'http://';
  $server = $_SERVER['SERVER_NAME'];
  $port = $_SERVER['SERVER_PORT'] ? ':'.$_SERVER['SERVER_PORT'] : '';
  return $protocol.$server.$port;
}

Answer 4

nothing worked serverside , something was wrong on APACHE and I had no access to the server and I ended up redirecting to http throught Javascript, It's not the ideal solution maybe this can save someone else in my situation

<script>
if(!window.location.href.startsWith('https')) 
    window.location.href = window.location.href.replace('http','https');
</script>

Answer 5

$_SERVER['SERVER_PORT'] will give you the port currently used.

Answer 6

<?php

$services = array('http', 'ftp', 'ssh', 'telnet', 'imap', 'smtp', 'nicname', 'gopher', 'finger', 'pop3', 'www');

foreach ($services as $service) {
    $port = getservbyname($service, 'tcp');
    echo $service . ":- " . $port . "<br />\n";
}

?>

This is display all port numbers.

If you already know port number you can do like this,

echo  getservbyport(3306, "http");   // 80
