Editing PHP using PHP (admin center)
<p>Am developing an admin center where I can edit configuration files (written in PHP). I do NOT want to store these values in a mySQL table (for various reasons). So say my config.php has contents like:</p>

<pre><code>   &lt;?php
     $option1 = 1;
     $option2 = 2;
     $option4 = 5;
     $option7 = array('test','a','b',c');
   ?&gt;
</code></pre>

<p>Now say in one of the admin pages I will only be changing a few values like option2 or option4 etc. Any ideas on what would be the best way to go about this.</p>

<p>I know one option is to read the PHP file completely and write parts of it using REGEX. Any way to make this more efficent? I don't want the config.php file to break because of some error on the user's end. Any ideas on how to ensure that it works?</p>
