Undefined variable error
<p>Hi I'm Denis and I'm new to php. My dad is a PHP developer but I want to do this on my own. I'm 11 years old now!!! :)</p>

<p>I made an installer for my php thing and I get this error:</p>

<pre><code>Notice: Undefined variable: config in \path\to\core.php on line 20
</code></pre>

<p>It's this part that is failing:</p>

<pre><code>$system['home_url'] = "".$config['home']['url']."";
</code></pre>

<p>But how can it fail if I included the config file before and this variable is not undefined!</p>

<p>I did: <code>require('config.php');</code></p>

<p>The config.php file code is:</p>

<pre><code>$config['home']['url'] = "http://localhost/";
</code></pre>

<p>Am I using the variables right? I searched all the internet and I only found solutions using <code>global</code> but I don't really know how it works..</p>

<p>Bye!!! and thanks:)))</p>

<p>EDIT--
Core.PHP</p>
