Simple abstractions for invoking functions with parameters.
Installation
Install with composer at krak/invoke
Usage
Each invoker implements the simple interface:
<?php interface Invoke { public function invoke($func, ...$args); }
Here's a simple example of the default invoker which uses call_user_func
.
<?php use Krak\Invoke; function hello($arg) { echo "Hello {$arg}\n"; } $invoke = new Invoke\CallableInvoke(); $invoke->invoke('hello', 'World');
Container Invoke
<?php // some psr container $container['service'] = function() {}; $invoke = Invoke\ContainerInvoke::create($container); $invoke->invoke('service'); // will invoke the function returned from the container $invoke->invoke('str_repeat', 'a', 10); // if not in container, will try to normally invoke
Container with Separator
In addition to just invoking services, you can invoke service object methods if you pass in a separator into the container factory method.
<?php $container['service'] = function() { return new ArrayObject([1]); }; $invoke = Invoke\ContainerInvoke::createWithSeparator($container, '@'); $invoke->invoke('service@count'); // retrieves the service and invokes the count method which outputs 1 in this case
Method Invoke
<?php // this will invoke any object with the append method $invoke = Invoke\MethodInvoke::create('append'); $data = new ArrayObject(); $invoke->invoke($data, 1); $invoke->invoke($data, 2); assert(count($data) == 2);
