title: Can I pass a DEFINED constant to a function through a variable in PHP?
body: <p>I have the following code:</p>
  
  <pre><code>DEFINE('DEFINEDTESTVAR', 'Hello World');
  
  function callit($callVar) {
    echo "The call is ".$callVar;
  }
  
  
  $passthis = 'DEFINEDTESTVAR';
  callit($passthis);
  </code></pre>
  
  <p>I know I can do <code>callit(DEFINEDTESTVAR)</code> but that's not what I am looking to do. Is it possible?</p>
