blocks|key|1321737|text|如果您想要获取散列标记或锚点之后的值，如用户浏览器中所示:这在“标准”超文本传输协议中是不可能的，因为这个值永远不会发送到服务器(因此它在$_SERVER["REQUEST_URI"]或类似的预定义变量中不可用)。您需要在客户端使用某种JavaScript魔术，例如将此值作为POST参数包含在内。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1321738|如果它只是解析来自任何来源的已知网址，那么answer+by+mck89是非常好用的。|1321739|entityMap|0|LINK|mutability|MUTABLE|url|https://stackoverflow.com/questions/2317508/php-get-value-from-url-after-sign/2317518#2317518^0|1X|N|0|L|F|0|0^^$0|@$1|2|3|4|5|6|7|P|8|@$9|Q|A|R|B|C]]|D|@]|E|$]]|$1|F|3|G|5|6|7|S|8|@]|D|@$9|T|A|U|1|V]]|E|$]]|$1|H|3|-4|5|6|7|W|8|@]|D|@]|E|$]]]|I|$J|$5|K|L|M|E|$N|O]]]]

<p>If you want to get the value after the hash mark or anchor as shown in a user's browser: This isn't possible with "standard" HTTP as this value is never sent to the server (hence it won't be available in <code>$_SERVER["REQUEST_URI"]</code> or similar predefined variables). You would need some sort of JavaScript magic on the client side, e.g. to include this value as a POST parameter.</p>

<p>If it's only about parsing a known URL from whatever source, the <a href="https://stackoverflow.com/questions/2317508/php-get-value-from-url-after-sign/2317518#2317518">answer by mck89</a> is perfectly fine though.</p>


blocks|key|1106538|text|这部分叫做“片段”，你可以这样获取它：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1106539|$url=parse_url("http://domain.com/site/gallery/1#photo45+");
echo+$url["fragment"];+//This+variable+contains+the+fragment|code-block|syntax|javascript|1106540|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

<p>That part is called "fragment" and you can get it in this way:</p>

<pre><code>$url=parse_url("http://domain.com/site/gallery/1#photo45 ");
echo $url["fragment"]; //This variable contains the fragment
</code></pre>


blocks|key|1106665|text|如果你坚持要用PHP赋值，我发现了这个窍门。拆分锚点(#)值并使用JavaScript获取它，然后存储为cookie，然后使用PHP获取Cookie值|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1106666|entityMap^0|R|1|0^^$0|@$1|2|3|4|5|6|7|H|8|@$9|I|A|J|B|C]]|D|@]|E|$]]|$1|F|3|-4|5|6|7|K|8|@]|D|@]|E|$]]]|G|$]]

<p>I found this trick if you insist want the value with PHP.
split the anchor (<code>#</code>) value and get it with JavaScript, then store as cookie, after that get the cookie value with PHP</p>

<p>Getting the data after the hashmark in a query string is simple. Here is an example used for when a client accesses a glossary of terms from a book. It takes the name anchor delivered (#tesla), and delivers the client to that term and highlights the term and its description in blue so its easy to see.</p>

<p>A. setup your strings with a div id, so the name anchor goes where its supposed to and the javascript can change the text colors </p>

<pre><code>&lt;div id="tesla"&gt;Tesla&lt;/div&gt;
&lt;div id="tesla1"&gt;An energy company&lt;/div&gt;
</code></pre>

<p>B. Use Javascript to do the heavy work, on the server side, inserted in your PHP page, or wherever..</p>

<pre><code>&lt;script src="http://code.jquery.com/jquery-1.9.1.min.js"&gt;&lt;/script&gt;
</code></pre>

<p>C. I am launching the java function automatically when the page is loaded. </p>

<pre><code>&lt;script&gt;
$( document ).ready(function() {
</code></pre>

<p>D. get the anchor (#tesla) from the url received by the server</p>

<pre><code>var myhash1 = $(location).attr('hash'); //myhash1 == #tesla
</code></pre>

<p>E. trim the hash sign off of it </p>

<pre><code>myhash1 = myhash1.substr(1)  //myhash1 == tesla
</code></pre>

<p>F. I need to highlight the term and the description so i create a new var </p>

<pre><code>var myhash2 = '1';
myhash2 = myhash1.concat(myhash2); //myhash2 == tesla1
</code></pre>

<p>G. Now I can manipulate the text color for the term and description</p>

<pre><code>var elem = document.getElementById(myhash1);
elem.style.color = 'blue';
elem = document.getElementById(myhash2);
elem.style.color = 'blue';
});
&lt;/script&gt;
</code></pre>

<p>H. This works. client clicks link on client side (xyz.com#tesla) and goes right to the term. the term and the description are highlighted in blue by javascript for quick reading .. all other entries left in black..</p>
