title: 'true' in Get variables
body: <p>In PHP, when you have something in the URL like "var=true" in the URL, does the 'true' and 'false' in the URL get translated to boolean variables, or do they equal the text 'true' or 'false'? For instance, would, with the url having "var=false" in it:</p>
  
  <pre><code>if ($_GET['var'] == false) { ... }
  </code></pre>
  
  <p>work? Or would the variable always be true since it has text in it?</p>
