title: Check if the image is a JPEG
body: <p>I need to check whether a given image is a JPEG.</p>
  
  <pre><code>if ($_FILES["fname"]["error"] &gt; 0) {
      $imgData = "hyperlink/holder.jpg";
  } else {
      $imgData ="hyperlink/" . $_FILES["fname"]["name"];
  }
  // Only accept jpg images
  // pjpeg is for Internet Explorer should be jpeg
  if (!($_FILES["fname"]["type"] == "image/pjpeg") ) {
      print "I only accept jpg files!";
      exit(0);
  }
  </code></pre>
  
  <p>When it goes to first statement in the first if statement it always gives I only accept jpg files!</p>
  
  <p>How can I fix it?</p>
