Relative URL's/paths in php
<p>Hi this is the first time I am asking a question here.</p>

<p>I have a image src as</p>

<pre><code>src="images//images/pixel.gif" 
</code></pre>

<p>But I dont understand this double forward slashes (<strong>//</strong>) in the src. </p>

<pre><code>src="./images/pixel.gif" 
src="../images/pixel.gif" 
</code></pre>

<p>Also what is the meaning of "<strong>./</strong>" and "<strong>../</strong>" in a relative file path.</p>
