From the diagram in the previous page, we know that index.php is the PHP script that handles user requests initially.

In a basic application, the index.php will contain minimal code as below:

include './protected/config/common.conf.php';
include './protected/config/routes.conf.php';
include $config['BASE_PATH'].'Doo.php';
include $config['BASE_PATH'].'app/DooConfig.php';

Doo::conf()->set($config);
Doo::app()->route = $route;
Doo::app()->run();

Basically, the index.php loads in common project settings and routes you have defined. Then, an instance of a web application is created with the configurations.

If you are using database ORM tool, you would have code as below:

include './protected/config/common.conf.php';
include './protected/config/routes.conf.php';
include './protected/config/db.conf.php';
include $config['BASE_PATH'].'Doo.php';
include $config['BASE_PATH'].'app/DooConfig.php';

# database usage
Doo::db()->setMap($dbmap);
Doo::db()->setDb($dbconfig, $config['APP_MODE']);
Doo::db()->sql_tracking = true;

Doo::conf()->set($config);
Doo::app()->route = $route;
Doo::app()->run();

The DB setMap() method is used for setting up tables relationship in the database. sql_tracking is used for logging down SQL queries executed in your app. You can retrieve the list of executed queries by writing the following code:

print_r( Doo::db()->show_sql() );

In production mode, you might want to use DooPHP's deploy script which combines several core classes of the framework in one file. It is optimized for performance.

include './protected/config/common.conf.php';
include './protected/config/routes.conf.php';
include './protected/config/db.conf.php';

include $config['BASE_PATH'].'deployment/deploy.php';

Doo::conf()->set($config);
Doo::db()->setMap($dbmap);
Doo::db()->setDb($dbconfig, $config['APP_MODE']);

Doo::app()->route = $route;
Doo::app()->run();

To have clean URls without 'index.php' you must enable mod_rewrite in Apache and in the .htaccess you would have:

RewriteEngine On

# if a directory or a file exists, use it directly
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d

# otherwise forward it to index.php
RewriteRule .* index.php
RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization},L]

There's a .htaccess.example in the app folder. Just rename it to .htaccess
