如何在 php 中创建友好的 URL?

Normally, the practice or very old way of displaying some profile page is like this:

www.domain.com/profile.php?u=12345

where u=12345 is the user id.

In recent years, I found some website with very nice urls like:

www.domain.com/profile/12345

How do I do this in PHP?

Just as a wild guess, is it something to do with the .htaccess file? Can you give me more tips or some sample code on how to write the .htaccess file?

According to this article, you want a mod_rewrite (placed in an .htaccess file) rule that looks something like this:

RewriteEngine on
RewriteRule ^/news/([0-9]+).html /news.php?news_id=$1

And this maps requests from

/news.php?news_id=63

to

/news/63.html

Another possibility is doing it with forcetype, which forces anything down a particular path to use php to eval the content. So, in your .htaccess file, put the following:

<Files news>
    ForceType application/x-httpd-php
</Files>

And then the index.php can take action based on the $_SERVER['PATH_INFO'] variable:

<?php
    echo $_SERVER['PATH_INFO'];
    // outputs '/63.html'
?>
