title: php error log save date-wise
body: <p>We want to monitor all php errors. We can check all errors with error_log file.
  Error logs files become so heavy. </p>
  
  <p>So it is very difficult to check errors in error_log file.</p>
  
  <p>Could it possible to write php error_log file on date-wise example '19-05_2015_error.log'</p>
  
  <p>or we can write error like "fetal.log" "notice.log"</p>
