title: printing a php variable as it is : with all the special characters
body: <p>Ok I need to find out what is contained inside a PHP variable and I have it to do it visually, is there a function to display whatever that's contained in a string as it is?</p>
  
  <p>For example : </p>
  
  <pre><code>$TEST = '&amp;nbsp' . "\n" . ' ';
  </code></pre>
  
  <p>if I use echo the output will be : </p>
  
  <p>while i want it to be :</p>
  
  <pre><code>&amp;nbsp\n&amp;nbsp
  </code></pre>
  
  <p>is it possible? (I hope I was clear enough)</p>
