Calling a function before it's defined | PHP
<p>Is there any possible way when in <strong>one</strong> file - please note, just one file. To call a function when it isn't defined yet, e.g.</p>

<pre><code>&lt;?php

echo global_title();

function global_title()
{
    $title = $_GET['name'];

    return $title;
}

?&gt;
</code></pre>

<p>I don't know how to explain this, but it's not quite possible isn't it? What about variable from another file (without including it) can be called in a different file, e.g.</p>

<p><strong>config.php</strong></p>

<pre><code>&lt;?php

$db = "localhost";

?&gt; 
</code></pre>

<p><strong>index.php</strong></p>

<pre><code>&lt;?php

// I do not want it to be accessed by including it or using sessions

echo $db;

?&gt;
</code></pre>

<p>Know what I mean? :)</p>
