In production, you should have error_reporting set to something like: E_ALL & ~E_DEPRECATED
And then:
display_errors = Off
display_startup_errors = Off
track_errors = Off
html_errors = Off
ignore_repeated_errors = Off
ignore_repeated_source = Off
log_errors = On
error_log = /path/to/log/file (or syslog)
Sorry bro, if you have ever put code on production with error reporting on...you are doing it wrong.
