Description 

Author

This class can be used to inject functionality in a class using other class or a closure function.

It allows creating a container object that will have functions from another given class that is injected in the container.

When the container object functions are called, this class calls the functions of the injected class.

DI Container

License: MIT

This library, resolves constructor & method dependency on the fly (also for closure). Check examples below.

Prerequisites

Language: PHP 7.0/+

Installation

composer require abmmhasan/di-container

Usage

Example 01: With additional parameter

/
* A test class where we resolving dependency for
* both constructor and defined method
*/
class TestClass
{
    public function __construct(Sample1 $sample, $id)
    {
        return [$sample->all(),$id];
    }

    public function getRequest(Sample2 $sample, $pid, $sid)
    {
        return [$sample->all(),$pid,$sid];
    }
}

/
* Pass the class as first parameter
* In second parameter pass the value as comma separated which will be
* resolved to class __construct
*/
$class = new Container(TestClass::class,23); // TestClass: Class we resolving, 23: $id param
// or,
$class = initiate(TestClass::class,23);
/
* Afterwards we call any methods of that class
* 'getRequest()' is a method of 'TestClass' that we are calling.
* Extra parameter can be sent as comma separated, which will be resolved to given method
*/
$value = $class->getRequest(34,43);

Example 02: Without additional parameter

/
* A test class where we resolving dependency for
* both constructor and defined method
*/
class TestClass
{
    public function __construct(Sample1 $sample)
    {
        return [$sample->all()];
    }

    public function getRequest(Sample2 $sample)
    {
        return [$sample->all()];
    }
}

/
* Only send parameter if required
*/
$class = new Container(TestClass::class); // TestClass: Class we resolving
// or,
$class = initiate(TestClass::class);
/
* Same as above
*/
$value = $class->getRequest();

Example 03: Closure

$myClosure = function (Request $request, $test, $rest) {
                     print_r($request);
                     echo "I'm inside[$test,$rest]";
                 };
$class = new Container($myClosure, 23, 34); // Pass the closure
// or,
$class = initiate($myClosure, 23, 34);

Example 04: I don't need any dependency resolution

/
* From example 02 (same for 01 but not applicable for 03: Closure)
 */
$class = new Container(TestClass::class); // TestClass: Class we resolving
// or,
$class = initiate(TestClass::class);
/
* Add this additional call before doing any method call
*/
$class->_noInject();
/
* Now do calls as usual
 */
$value = $class->getRequest();
