使用PHP或JS检查域扩展

Question

First of all I am a php beginner so please be as specific as possible. Basically I want a php/javascript that does the following:

if the domain has a .de extension then add the text "this is a german site" else add the text "this is not a german site"

it's also ok if you do it with the lang="de-DE" instead of the domain extension.

Answer 1

To get the domain extension use php's pathinfo

$extension = pathinfo($_SERVER['SERVER_NAME'], PATHINFO_EXTENSION);

if($extension == "de")
{
echo "this is a german site";
}

Also see: $_SERVER

Answer 2

In PHP, try something like this:

<?php
//~ $domain = $_SERVER['HTTP_HOST'];
$domain = "domain.de";

if (preg_match('/(.*?)\.de$/', $domain)) {
    echo "is german";
} else {
    echo "is not german";
};
?>

Greatings.

Answer 3

var isDE="";
var extension=location.hostname.split(".");
extension=extension[extension.length-1];
if (extension=="de") isDE="this is a german site".
//do whatever you need with isDE, e.g. document.write(isDE);
