title: Xdebug profiler not writing files
body: <p>I'm using MAMP, and I have xdebug enabled in the extensions tab. Debugging works fine, but the profiler doesn't write to any files.</p>
  
  <p><strong>php.ini</strong></p>
  
  <pre><code>[xdebug]
  ;zend_extension="/Applications/MAMP/bin/php/php7.0.20/lib/php/extensions/no-debug-non-zts-20151012/xdebug.so"
  xdebug.profiler_enable = 0;
  xdebug.profiler_enable_trigger = 1;
  xdebug.profiler_output_dir = "/Users/jordyvandomselaar/workspace/xdebug/profiler/snapshots"
  </code></pre>
  
  <p>I have the xdebug extension, and it's toggle on "profiler". I've <code>chmod</code>ded the output folder to <code>777</code> to be sure it's not a permission issue.</p>
  
  <p>Anything I missed?</p>
