title: Is it possible to make php report errors only to the errorlog?
body: <p>As title describes.</p>
  
  <p>My sites have been moved to a newer environment, and some non-crititcal errors has come up.
  I want to suppress all the warnings on the websites, but still want them to be logged to the standard error_log, so i can fix the errors without my sites looking non-functional.</p>
  
  <p>Is there some easy way to do that?</p>
