Clean URLs with PHP [duplicate]

How to create friendly URL in php? (8 answers)

Closed 10 months ago.

So I am trying to build a clean url system in PHP to change URLS like this http://example.com/index.php?projects=05 to: http://example.com/projects/05

So far, I have figured out how to use parse_url to map urls that look like http://example.com/index.php/projects/05 but I can't figure out how to remove the 'index.php' from the URL. Is there a way to use .htaccess to remove index.php from the url string?

I know this is sort of a simple problem but after extensive googling, I can't find a solution.

回答1:

You'll need to do this in Apache using mod_rewrite. You'll need to redirect all URLs to to your index.php and then, maybe using parse_url, figure out what to do with them.

For example:

# Turn on the rewrite engine
RewriteEngine On

# Only redirect if the request is not for index.php
RewriteCond %{REQUEST_URI} !^/index\.php

# and the request is not for an actual file
RewriteCond %{REQUEST_FILENAME} !-f

# or an actual folder
RewriteCond %{REQUEST_FILENAME} !-d

# finally, rewrite (not redirect) to index.php
RewriteRule .* index.php [L]

I am using the following .htaccess file to remove the index.php part of the url.

# Turn on URL rewriting
RewriteEngine On

# Installation directory
RewriteBase /

# Protect hidden files from being viewed
<Files .*>
    Order Deny,Allow
    Deny From All
</Files>

# Allow any files or directories that exist to be displayed directly
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !favicon.ico$

RewriteRule .* index.php/$0 [PT]

Otherwise I can recommend the Kohana framework as a reference (they also have a fairly nice url parser and controller system)

回答3:

The concept of decoupling the actual files/folders from the URL is called routing. Many PHP frameworks include this kind of functionality, mostly using mod_rewrite. There is a nice blog post on PHP URL Routing that implements a simple standalone router class.

It creates mapping like this:

mysite.com/projects/show/1 --> Projects::show(1)

So the requested URL results in the function show() of the class Projects being called, with the parameter of 1.

You can use this to build flexible mappings of pretty URLs to your PHP code.

Something like this in your .htaccess :

RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.*)$ index.php [QSA,L]

(Be sure the rewrite module is enabled)
