  <p>I want to create a function with several parameters that one of them has several constant variable.
  for example:</p>
  
  <pre><code>&lt;?php
  function print($str, $num){...}
  .
  .
  .
  print("omid",one);
  print("omid",two);
  ?&gt;
  </code></pre>
  
  <p>in this example $num consist of constant variable:"one,two, three"
  Now, how to implement it? is there Enum in php?</p>
  
  <p>thanks your time</p>
