Calling a method of an instance of a class
<p>Forgive me for asking such a novice question, but I can't figure out how to call a method in PHP.  Here's what I'm trying to do (in pseudocode):</p>

<pre><code>class Thing {
    public string Color() {
        return "taupe";
    }
}

Thing x = new Thing();
echo x.Color();
</code></pre>

<p>This should echo <code>taupe</code> as its result.  The part I'm getting stuck on is the last line: invoking the <code>Color</code> method of <code>x</code>.  How does one do this in PHP?</p>
