blocks|key|1681630|text|与上面的答案一样，您需要启用mod_rewrite，然后在.htaccess文件中提供映射模式。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1681631|我认为您还必须确保将虚拟主机配置为|1681632|`Allow+Override+ALL`|code-block|syntax|javascript|1681633|这个页面提供了很好的细节-向下滚动到题为“如何重写urls”的部分。|1681634|http://www.smashingmagazine.com/2011/11/02/introduction-to-url-rewriting/|offset|length|1681635|entityMap|0|LINK|mutability|MUTABLE|url^0|0|0|0|0|0|21|0|0^^$0|@$1|2|3|4|5|6|7|V|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|W|8|@]|9|@]|A|$]]|$1|D|3|E|5|F|7|X|8|@]|9|@]|A|$G|H]]|$1|I|3|J|5|6|7|Y|8|@]|9|@]|A|$]]|$1|K|3|L|5|6|7|Z|8|@]|9|@$M|10|N|11|1|12]]|A|$]]|$1|O|3|-4|5|6|7|13|8|@]|9|@]|A|$]]]|P|$Q|$5|R|S|T|A|$U|L]]]]

Like the answer above - you need to enable mod_rewrite and then provide the mapping pattern inside your .htaccess file.

I believe you also have to ensure that your Virtual Host is configured to 

<pre><code>`Allow Override ALL`
</code></pre>

If you really want to do it yourself and that's fine if you do, this is an example of what you will need to do. I understand not everyone needs or wants to use a framework.

First lets say your user URL is this like Github example. 

<pre><code>http://www.yoursite.com/user/dmitrij 
</code></pre>

Then to for your .htaccess you will need a rewrite rule like this.

<pre><code> RewriteEngine On
 # check to make sure the request is not for a real file
 RewriteCond %{REQUEST_FILENAME} !-f
 # check to make sure the request is not for a real directory
 RewriteCond %{REQUEST_FILENAME} !-d
 #route request to index.php
 RewriteRule ^user/([^/]+)/? /user/index.php?id=$1 [L]
</code></pre>

Then if you want to show comments, your URL can look like this

<pre><code>http://www.yoursite.com/user/dmitrij/comments/32
</code></pre>

Then it you can use .htaccess 

<pre><code> RewriteEngine On
 # check to make sure the request is not for a real file
 RewriteCond %{REQUEST_FILENAME} !-f
 # check to make sure the request is not for a real directory
 RewriteCond %{REQUEST_FILENAME} !-d
 #route request to index.php
 RewriteRule ^user/([^/]+)/comments/([0-9]+)/? /user/index.php?id=$1&amp;comment_id=$2 [L]
</code></pre>

Then you can put them all together in your .htaccess file for both URL's.

<pre><code> RewriteEngine On
 RewriteCond %{REQUEST_FILENAME} !-f
 RewriteCond %{REQUEST_FILENAME} !-d
 RewriteRule ^user/([^/]+)/comments/([0-9]+)/? /user/index.php?id=$1&amp;comment_id=$2 [L]
 RewriteCond %{REQUEST_FILENAME} !-f
 RewriteCond %{REQUEST_FILENAME} !-d
 RewriteRule ^user/([^/]+)/? /user/index.php?id=$1 [L]
</code></pre>

Then in your <code>index.php</code> you will check the <code>$_GET</code> request. This is a very simple example.

<pre><code>&lt;?php

 $username = $_GET["id"];
 $com_id = $_GET["comment_id"];

 print_r($username);
 exit;

?&gt;
</code></pre>

Make sure <code>mod_rewrite</code> is enabled on the server and <code>AllowOverride All</code> is set in your vhost or config file. 

You can do whatever you want with the values in <code>$_GET</code>. You will have to ensure <code>username</code> is unique in your database. You can also add more rewrites for different URL's too, which I wont cover here. 
This should get you a good start.

In my web server document root i have created folder <code>/user/</code> with <code>/index.php</code> script in it. Regardless the current (authorized) user, i need to make a page which displays information about any users on my site to anyone, i have an idea to use query string:

<pre><code>site.com/user/?id=3
</code></pre>

But i don't want to do like this. I want GitHub-like urls, like this:

<pre><code>site.com/user/UserName/
</code></pre>

Also, i need to allow URL continutation to specify which 'action' is requested, like <code>subscribe</code>, or <code>comments</code>, and parameters, for specified username:

<pre><code>site.com/user/Admin/comments/32
site.com/user/Admin/virtual/path/
</code></pre>

which should be a simple rewrite to physical path: `/user/index.php'.

I am newbie in PHP, but i know basics of mod_rewrite and .htaccess, and i still don't understand how can i determine which user (<code>Admin</code>) and what action (<code>comments</code>) is requested by URL, in my PHP script <code>index.php</code>.

Please teach how can i reach this URL syntax for my site? Or better, how to redirect <code>/user/Admin/comments</code> to physical <code>/user/comments.php</code>..

<ol>
<li>How to set up such dynamic rewriting with saving the username/action for php script?</li>
<li>How script can access user name and action (<code>comments</code>, <code>32</code>) requested by URL</li>
<li>How should i rename my question, because this title seems to be incorrect.</li>
</ol>

Sorry for long text, i am new in clean PHP scripting, Thanks!

How do i script dynamic URLs for my site with php?
