RequirePHP

An implementation of dependency injection and service locator (like RequireJS) in PHP.

Installation

You can install RequirePHP with Composer or Bower.

composer require sciactive/requirephp

bower install https://github.com/sciactive/requirephp.git

Getting Started

If you don't use an autoloader, all you need to do is include the RequirePHP.php file.

require("RequirePHP.php");

Now you can start giving code that requires a module, or modules, to run. This code will not run until all the required modules (in this case, only 'test') are available.

\SciActive\RequirePHP::_(array('test'), function($test){
	$test->value = '<p>Hello, world.</p>';
});

You can define modules. This module has no dependencies, hence the empty array.

\SciActive\RequirePHP::_('test', array(), function(){
	class test {
		public $value;

		public function talk() {
			echo $this->value;
		}
	}

	// Returning a new instantiation is important if you are
	// providing a service.
	return new test();
});

You can create aliases to modules (and other aliases).

\SciActive\RequirePHP::alias('testing', 'test');

You can keep using the same instance in other code, using RequirePHP as a service locator. This function uses the alias from above.

\SciActive\RequirePHP::_(array('testing'), function($test){
	$test->talk(); // Prints '<p>Hello, world.</p>'.
});

You can also retrieve modules outside of a closure. However, if this module is not available at the time you request it, RequirePHP will throw a RequireModuleFailedException. Such is the price of not using a closure.

$test = \SciActive\RequirePHP::_('test');
$test->talk(); // Prints '<p>Hello, world.</p>'.

Service Location

The repository contains an example of using RequirePHP as a service locator.

Dependency Injection

The repository contains an example of using RequirePHP as a dependency injector.
