Class instantiation Syntax - Can't understand it
<p>I am New to PHP and reading these day "PHP in Action" book
is good. But what i don't understand is its Class Initiation syntax.</p>

<p>it uses often a syntax like</p>

<pre><code>$config = new Config;
</code></pre>

<p>can someone please explain why he is  instantiating like this, i mean without parentheses?</p>

<p>And is there are goog PHP book available to learn OOP with assignments?</p>
