• By default, all errors included in error_reporting are reported in php´s output

• This behavior can – and should – be deactivated on production systems using the display_errors = off php.ini setting

• Errors should still be logged, using the log_errors = on php.ini setting

• The error log is a file set in the error_log php configuration setting. if set to syslog, errors are logged in the system log independent on the operating system used.
