title: Delete particular word from string
body: <p>I'm extracting twitter user's profile image through JSON. For this my code is:</p>
  
  <pre><code>$x-&gt;profile_image_url
  </code></pre>
  
  <p>that returns the url of the profile image. The format of the url may be <code>"..xyz_normal.jpg"</code> or <code>"..xyz_normal.png"</code> or <code>"..xyz_normal.jpeg"</code> or <code>"..xyz_normal.gif"</code> etc.</p>
  
  <p>Now I want to delete the "_normal" part from every url that I receive. How can I achieve this in php? I'm tired of trying it. Please help.</p>
