It is typical to use the front-controller pattern to funnel appropriate HTTP requests received by your web server to a single PHP file. The instructions below explain how to tell your web server to send HTTP requests to your PHP front-controller file.

PHP built-in server

Run the following command in terminal to start localhost web server, assuming ./public/ is public-accessible directory with index.php file:

php -S localhost:8080 -t ./public/

Apache configuration

Ensure your .htaccess and index.php files are in the same public-accessible directory. The .htaccess file should contain this code:

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

Make sure your Apache virtual host is configured with the AllowOverride option so that the .htaccess rewrite rules can be used:

AllowOverride All

Nginx configuration

This is an example Nginx virtual host configuration for the domain example.com. It listens for inbound HTTP connections on port 80. It assumes a PHP-FPM server is running on port 9000. You should update the server_name, error_log, access_log, and root directives with your own values. The root directive is the path to your application’s public document root directory; your Slim app’s index.php front-controller file should be in this directory.

server {
    listen 80;
    server_name example.com;
    index index.php;
    error_log /path/to/example.error.log;
    access_log /path/to/example.access.log;
    root /path/to/public;

    location / {
        try_files $uri $uri/ /index.php$is_args$args;
    }

    location ~ \.php {
        try_files $uri =404;
        fastcgi_split_path_info ^(.+\.php)(/.+)$;
        include fastcgi_params;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        fastcgi_param SCRIPT_NAME $fastcgi_script_name;
        fastcgi_index index.php;
        fastcgi_pass 127.0.0.1:9000;
    }
}

HipHop Virtual Machine

Your HipHop Virtual Machine configuration file should contain this code (along with other settings you may need). Be sure you change the SourceRoot setting to point to your Slim app’s document root directory.

Server {
    SourceRoot = /path/to/public/directory
}

ServerVariables {
    SCRIPT_NAME = /index.php
}

VirtualHost {
    * {
        Pattern = .*
        RewriteRules {
                * {
                        pattern = ^(.*)$
                        to = index.php/$1
                        qsa = true
                }
        }
    }
}

IIS

Ensure the Web.config and index.php files are in the same public-accessible directory. The Web.config file should contain this code:

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
    <system.webServer>
        <rewrite>
            <rules>
                <rule name="slim" patternSyntax="Wildcard">
                    <match url="*" />
                    <conditions>
                        <add input="{REQUEST_FILENAME}" matchType="IsFile" negate="true" />
                        <add input="{REQUEST_FILENAME}" matchType="IsDirectory" negate="true" />
                    </conditions>
                    <action type="Rewrite" url="index.php" />
                </rule>
            </rules>
        </rewrite>
    </system.webServer>
</configuration>

lighttpd

Your lighttpd configuration file should contain this code (along with other settings you may need). This code requires lighttpd >= 1.4.24.

url.rewrite-if-not-file = ("(.*)" => "/index.php/$0")

This assumes that Slim’s index.php is in the root folder of your project (www root).
