For production use, you don’t want to show your PHP errors to end users, but you do want to log them for evaluation later. To do so, change the php.ini file and create the following configs.
display_errors = Off display_startup_errors = Off html_errors = Off log_errors = On error_log = /var/log/php_errors.log error_reporting = E_ALL & ~E_DEPRECATED
The configuration above will deny all PHP errors being shown to your visitors but will log them all to the logfile shown above.
If you prefer to log them to syslog, change the error_log variable as shown below.
error_log = syslog
Don’t forget to restart Apache if you’re using mod_php or restart your php-fpm service after making changes to the php.ini configs.
