title: one php file for all jquery post requests?
body: <p>I have a lot of jquery ajax methods and for each of them a small php file.<br>
  Is it possible to create one single php file and than on jquery side refer to a specific function in the php file?<br>
  Like this:</p>
  
  <pre><code>$.ajax({
      type: "POST",
      url: "functions.php", function01(),
      ....
  </code></pre>
  
  <p>next function:  </p>
  
  <pre><code>$.ajax({
      type: "POST",
      url: "functions.php", function02(),
      .... 
  </code></pre>
  
  <p>And if it is possible - is it maybe a wrong practice for overall performance? </p>
