title: How to make control characters visible in string?
body: <p>I was wondering if it is possible to make control characters in a string visible.</p>
  
  <pre><code>    $mystring = "Test\n";
      echo $mystring;
  </code></pre>
  
  <p>This will output <code>Test</code> but i don't want PHP to translate <code>\n</code> it should just output <code>Test\n</code> (For debugging purposes). Is this possible?</p>
