Is there a way to output the definition of a function in PHP?
<pre><code>function func() {
    // ...
}
</code></pre>

<p>I have the function name <code>"func"</code>, but not its definition.</p>

<p>In JavaScript, I'd just use <code>alert()</code> to see the definition.</p>

<p>Is there a similar function in PHP?</p>
