PHP getting full server name including port number and protocol
提问by ale
In PHP, is there a reliableand good way of getting these things:
在 PHP 中，是否有一种可靠且好的方法来获得这些东西：
Protocol: i.e. http or https Servername: e.g. localhost Portnumber: e.g. 8080
协议：即 http 或 https 服务器名称：例如 localhost 端口号：例如 8080
I can get the server name using $_SERVER['SERVER_NAME'].
我可以使用$_SERVER['SERVER_NAME'].
I can kind of get the protocol but I don't think it's perfect:
我可以得到协议，但我认为它并不完美：
if(strtolower(substr($_SERVER["SERVER_PROTOCOL"],0,5))=='https') {
return "https";
}
else {
return "http";
}
I don't know how to get the port number though. The port numbers I am using are not 80.. they are 8080 and 8888.
我不知道如何获取端口号。我使用的端口号不是 80.. 它们是 8080 和 8888。
Thank you.
谢谢你。

Have a look at the documentation.
查看文档。
You want $_SERVER['SERVER_PORT']I think.
你要$_SERVER['SERVER_PORT']我想。

$_SERVER['SERVER_PORT']will give you the port currently used.
$_SERVER['SERVER_PORT']会给你当前使用的端口。

Here's what I use:
这是我使用的：
function my_server_url()
{
$server_name = $_SERVER['SERVER_NAME'];
if (!in_array($_SERVER['SERVER_PORT'], [80, 443])) {
$port = ":$_SERVER[SERVER_PORT]";
} else {
$port = '';
}
if (!empty($_SERVER['HTTPS']) && (strtolower($_SERVER['HTTPS']) == 'on' || $_SERVER['HTTPS'] == '1')) {
$scheme = 'https';
} else {
$scheme = 'http';
}
return $scheme.'://'.$server_name.$port;
}

<?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.
这是显示所有端口号。
If you already know port number you can do like this,
如果你已经知道端口号，你可以这样做，
echo getservbyport(3306, "http"); // 80

Compiled from above:
从上面编译：
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;
}

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

if(strtolower(substr($_SERVER["SERVER_PROTOCOL"],0,4))=='http') {
$strOut = sprintf('http://%s:%d',
$_SERVER['SERVER_ADDR'],
$_SERVER['SERVER_PORT']);
} else {
$strOut = sprintf('https://%s:%d',
$_SERVER['SERVER_ADDR'],
$_SERVER['SERVER_PORT']);
}
return $strOut;
Try something like that if you want
如果你愿意，试试这样的事情
回答by Jonathan dos Santos
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
服务器端没有任何工作，APACHE 出现问题，我无法访问服务器，我最终通过 Javascript 重定向到 http，这不是理想的解决方案，也许这可以在我的情况下拯救其他人
<script>
if(!window.location.href.startsWith('https'))
window.location.href = window.location.href.replace('http','https');
</script>

Why don't you get full url like this
你为什么不得到这样的完整网址
strtolower(array_shift(explode("/",$_SERVER['SERVER_PROTOCOL'])))."://".$_SERVER['SERVER_NAME'];
or (If you want host name from HTTP)
或（如果您想要来自 HTTP 的主机名）
strtolower(array_shift(explode("/",$_SERVER['SERVER_PROTOCOL'])))."://".$_SERVER['HTTP_HOST'];
