Find htdocs path, no matter where file is stored
<p>How can I find my htdocs directory.</p>

<p>When I execute the following command:</p>

<pre><code>echo  dirname(__FILE__);
</code></pre>

<p>I get the following output:</p>

<pre><code>/var/www/myexample.com/htdocs/required/css
</code></pre>

<p>I want to find path till /htdocs, but I don't want to hard-code the things</p>

<p>I know I can use:</p>

<pre><code>dirname(dirname(dirname(__FILE__)))
</code></pre>

<p>But, that will work if the current file is in "css" directory. If I will move to some other directory inside "css" directory, then it will not work.</p>

<p>Any solution for this?</p>
