title: Pass parameter containing `&` with AJAX
body: <p>I am passing my string to PHP through AJAX using <code>$.Ajax</code>.</p>
  
  <p>I'm trying to pass this string: </p>
  
  <pre><code>action=abc&amp;parameter=C&amp;W
  </code></pre>
  
  <p>The AJAX splits the <code>C&amp;W</code> on the basis of <code>&amp;</code>, so the request comes in this format:</p>
  
  <pre><code>$action = "abc";
  $parameter = "C";
  </code></pre>
  
  <p>How can I pass it as <code>C&amp;W</code>, without it being split into a different parameter?</p>
