Answer 1

Prevent no. But catch and log yes, using register_shutdown_function()

See PHP manual

function shutDown_handler()
{
   $last_error = error_get_last();
   //verify if shutwown is caused by an error
   if (isset ($last_error['type']) && $last_error['type'] == E_ERROR)
   {
      /*
        my activity for log or messaging
        you can use info: 
          $last_error['type'], $last_error['message'],
          $last_error['file'], $last_error['line']
          see about on the manual PHP at error_get_last()
      */
   }
}

register_shutdown_function ('shutDown_handler');
