I got two index.php and both make use of a bootstrap.php. The bootstrap file is setting up a DI-Container and I need in both index files access to this DI-Container.
First I was thinking about using a simple return in bootstrap.php:
bootstrap.php
<?php
require __DIR__ . '/vendor/autoload.php';
$container = new League\Container\Container;
// add some services
return $container;
index.php
<?php
$container = require __DIR__ . '/bootstrap.php';
$container->get('application')->run();
I read somewhere that using return statements like this are a bad habit. So I'm wondering how to make the container in the index.php accessible in an easy and proper way?
There is no need for a return, if you include the file you already have the access to the variable $container
bootstrap.php
<?php
require __DIR__ . '/vendor/autoload.php';
$container = new League\Container\Container;
// add some services
index.php
<?php
require __DIR__ . '/bootstrap.php';
$container->get('application')->run();
UPDATED (following the comments):
bootstrap.php
<?php
require __DIR__ . '/vendor/autoload.php';
// add some services
return new League\Container\Container;
index.php
<?php
$container = require __DIR__ . '/bootstrap.php';
$container->get('application')->run();
ANOTHER EXAMPLE:
If you need to add your services on the Container object before return, you can use a static helper class (just for example) if you want to avoid a global variable:
class Context {
private static $container = null;
public static function getContainer() {
return self::$container;
}
/* maybe you want to use some type hinting for the variable $containerObject */
public static function setContainer( $containerObject ) {
self::$container = $containerObject;
}
}
bootstrap.php
<?php
require __DIR__ . '/vendor/autoload.php';
// require the Context class, or better get it with your autoloader
Context::setContainer( new League\Container\Container );
// add some services
Context::getContainer()->addMyService();
Context::getContainer()->addAnotherService();
//if you want to, you can return just the container, but you have it in your Context class, so you don't need to
//return Context::getContainer();
index.php
<?php
require __DIR__ . '/bootstrap.php';
Context::getContainer()->get('application')->run();
