You can't get this value with PHP because PHP processes things server-side, and the hash in the URL is client-side only and never gets sent to the server. JavaScript canget the hash though, using window.location.hash(and optionally call on a PHP script including this information, or add the data to the DOM).
您无法使用 PHP 获取此值，因为 PHP 在服务器端处理事物，并且 URL 中的哈希值仅在客户端使用，永远不会发送到服务器。JavaScript可以获取哈希，使用window.location.hash（和可选地调用包含此信息的 PHP 脚本，或将数据添加到 DOM）。

Just adding onto @Alec's answer.
只是添加到@Alec 的答案中。
There is a parse_url()function:
有一个parse_url()功能：
Which can return fragment - after the hashmark #. However, in your case it will return allvalues after the hashmark:
哪个可以返回fragment - after the hashmark #。但是，在您的情况下，它将返回哈希标记后的所有值：
Array
(
[path] => catalog.php
[fragment] => album=2song=1
)
As @NullUserException pointed out, unless you have the url beforehand this really is pointless. But, I feel its good to know nonetheless.
正如@NullUserException 指出的那样，除非您事先拥有 url，否则这确实毫无意义。但是，我觉得还是很高兴知道。

You can use AJAX/PHP for this. You can get the hash with javaScript and load some contents with PHP. Let's suppose we're loading the main content of a page, so our URL with hash is "http://www.example.com/#main":
您可以为此使用 AJAX/PHP。您可以使用 javaScript 获取哈希并使用 PHP 加载一些内容。假设我们正在加载页面的主要内容，因此带有哈希值的 URL 是“ http://www.example.com/#main”：
JavaScript in our head:
我们脑海中的 JavaScript：
function getContentByHashName(hash) { // "main"
// some very simplified AJAX (in this example with jQuery)
$.ajax({
url: '/ajax/get_content.php?content='+hash, // "main"
success: function(content){
$('div#container').html(content); // will put "Welcome to our Main Page" into the <div> with id="container"
}
});
}
var hash=parent.location.hash; // #main
hash=hash.substring(1,hash.length); // take out the #
getContentByHashName(hash);
The PHP could have something like:
PHP 可能有以下内容：
<?php
// very unsafe and silly code
$content_hash_name = $_GET['content'];
if($content_hash_name == 'main'):
echo "Welcome to our Main Page";
endif;
?>
