Redirecting php error message to a log file
Author: danielMay 7
By default, any error message in your php script will be visible to site visitors on the browser and will be logged to apache error log file – most commonly in “/var/log/httpd/error.log”. In a production server it is advisable to prevent the error message from appearing on browser and has to be silently sent to a custom log file, specifically created for logging only php error messages. Following these steps might help:
1. Create the file under /var/log –
$touch /var/log/php-error.log
2. change permission to 644 –
$chmod 644 /var/log/php-error.log
3. set ownership –
$chown root.apache /var/log/php-error.log
(if httpd is running under apache, could be www-data, nobody…)
4. Edit /etc/php.ini and make sure the following options are set correctly
error_reporting = E_ALL display_errors = OFF error_log =/var/log/php-error.log log_errors = ON
5. Write a php script with some syntax error in it and check whether the error notification is logged or not
$tail -f /var/log/php-error.log
