title: PHP 7 - Exception does not get logged in error_log. error_log not geterated at all
body: <p>Following PHP code is run with PHP7:</p>
  
  <pre><code>&lt;?php
  
  ini_set('log_errors',1);
  
  error_reporting(0);
  
  throw new Exception('some exception here');
  
  ?&gt;
  </code></pre>
  
  <p>Exception is thrown, but not 'catch'-ed.</p>
  
  <p>Why the '<strong>error_log</strong>' file is not generated? Does <strong>error_reporting(0)</strong> suppress exceptions too?</p>
  
  <p>Removing the '<strong>error_reporting(0)</strong>' produces the error_log file, as expected.</p>
  
  <p>How can I log uncaught exceptions only in error_log but suppress other errors with error_reporting(0)?</p>
