htaccess和php - 重定向和漂亮的网址

Question

I have a webcommunity, and it's growing now. I like to do a link makeover for my web, and then I need to know the best solution for my case.

Right now my htaccess looks kind of like this:

RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^([^/\.]+)/?$ index.php?page=user&username=$1 [L]

You are able to link to users like this domain.com/username and that's nice.

Then I have different pages like

• index.php?page=forum&id=1
• index.php?page=someotherpage&id=1&anotherid=5
• index.php?page=3rd

... and so on. I want them to look something like this:

• domain.com/forum/23/title-of-the-thread
• domain.com/page2/id1/id2

... and so on.

How do I make these pretty urls without removing my domain.com/username functionality? What solution would you suggest?

I was thinking about creating a file that checks the URL, if it matches any pages, and users and so on. Then it will redirect with a header location.

Answer 1

If all of the urls you are going to rewrite are going to the same end point, you could simply use:

RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^ index.php [L]

in index.php:

<?php
$url = $_SERVER['REQUEST_URI'];

How you use the request uri is up to you, you could for example use a simple strpos check:

<?php
$url = $_SERVER['REQUEST_URI'];

$rules = array(
    '/forum/' => 'forum',
    '/foo/' => 'foo',
    '/' => 'username'
);

foreach($rules as $pattern => $action) {
    if (strpos($url, $pattern) === 0) {
        // use action
        $file = "app/$action.php";
        require $file; 
        exit;
    }
}
// error handling - 404 no route found
