<p>To avoid 'headers already sent' error message can I use obstart before session start in PHP, like below:</p>

<pre><code>// db information here
ob_start();
session_start();
</code></pre>

<p>Is this a good practice to use in every PHP project to avoid 'header already sent error' or it is for special cases?</p>
