How does the php snippet work?
<pre><code> $this-&gt;_config = parse_ini_file($configIniFile);
</code></pre>

<p>And this is the content of <code>$configIniFile</code>：</p>

<pre><code>; &lt;?php exit; ?&gt; DO NOT REMOVE THIS LINE
[database]
host                 = localhost
username             = root
password             = 
dbname               = openslopeone
port                 = 3306
adapter              = PDO_MYSQL ; PDO_MYSQL or MYSQLI
</code></pre>
