title: Relative URL's/paths in php
body: <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>
  
  <p>Also what is the meaning of "<strong>./</strong>" and "<strong>../</strong>" in a relative file path like in below src:</p>
  
  <pre><code>src="./images/pixel.gif" 
  src="../images/pixel.gif" 
  </code></pre>
