    }

invoke()

$callback->invoke($arg1, $arg2, $arg3);

invokeArguments()

$callback->invokeArguments($arrayArguments);

__invoke()

$callback($arg1, $arg2, $arg3); // call_user_func() and call_user_func_array() will work like a charm

Arguments

This library provides more flexibility when defining the arguments to be used when you call your callback. That's useful when you working with callbacks in a predefined structure but you don't want all arguments., _(*7)

Names

Callback will execute your callback based on its parameters name., _(*8)

$callable = new Callback(
    function ($foo, $bar = true) {
        // My callable body
    }
);
$callable->invokeArguments(
    array(
        'foo' => 'PHPFluent',
    )
);

Types

Doesn't matter the order of the arguments, Callback will put it in the right order before execute your callable., _(*9)

$callable = new Callback(
    function (array $array, TypeTwo $typeTwo, $string, $int, TypeThree $typeThree, $optional = 42) {
        // My callable body
    }
);
$callable(array(), new TypeTwo(), new TypeThree(), 'string', 123);
