title: How to use $_GET[] in wordpress template?
body: <p>I try to use the $_GET[] array in a wordpress template page but I keep getting this error when I use it :</p>
  
  <blockquote>
    <p>Fatal error: Can't use function return value in write context in ... on line ...</p>
  </blockquote>
  
  <p>If I comment every call to $_GET, the page displays without error.</p>
  
  <p>How can I use the $_GET array in this case?</p>
  
  <p>Thanks</p>
