adding additional settings to $_ENV
<p>I am writing this CMS, and I'd like to know if there's any disadvantages of adding additional values to the global $_ENV variable. </p>

<p>Example; </p>

<pre><code>$_ENV['baseURL'] = 'http://www.example.org'; 
</code></pre>

<p>I want to do so, because I want the variable i keep settings to be global automatically. 
I think it's a good way. Do you agree? if not, why? I'm curious if there's any disadvantages. </p>
