<?php

use Prob\Handler\ProcFactory;

$proc = ProcFactory::getProc('testFunc', 'Apple\\Banana');
print_r($proc->exec('one', 'two', 'three'));        // Array ( 'three', 'two', 'one' )

someFunc.php, _(*3)

<?php

namespace Apple\Banana;

function testFunc($a, $b, $c)
{
    return [$c, $b, $a];
}

calling class method

<?php

use Prob\Handler\ProcFactory;

class Orange
{
    public function testFunc($a, $b)
    {
        return $a + $b;
    }
}

binding parameters

<?php

use Prob\Handler\ProcFactory;
use Prob\Handler\ParameterMap;
use Prob\Handler\Parameter\Named;
use Prob\Handler\Parameter\Typed;
use Prob\Handler\Parameter\TypedAndNamed;

use Apple\Banana\ValueObject;

$proc = ProcFactory::getProc('testFuncWithBinding', 'Apple\\Banana');

$vo = new ValueObject();
$vo->value = 'Welcome ';

$parameterMap = new ParameterMap();
$parameterMap->bindBy(new Named('arg3'), 'World!');
$parameterMap->bindBy(new Typed('array'), ['str' => 'Hello']);
$parameterMap->bindBy(new TypedAndNamed(ValueObject::class, 'arg1'), $vo);

// Welcome HelloWorld!
echo $proc->execWithParameterMap($parameterMap);

someFuncWithBinding.php, _(*5)

<?php

namespace Apple\Banana;

function testFuncWithBinding(ValueObject $arg1, array $arg2, $arg3)
{
    return $arg1->value . $arg2['str'] . $arg3;
}

class ValueObject
{
    public $value;
