How does php output errors to a file?

Input PHP errors into the log file

(LAMP) prevent client browsers from displaying PHP code errors and save error messages to log files:

Find php.ini in the php configuration file (such as in / etc/php.ini under Centos6.7), and set

Display_errors = Off / / error messages are not allowed to be displayed in browsers log_errors = On / / input error messages into log files error_log = / var/www/html/php_errors_log// specify error log location

Find the configuration file http.conf of apache (such as / etc/httpd/conf/httpd.conf under Centos6.7), and set

Php_flag display_errors off php_value error_reporting 2039

Restart the apache server

Service httpd restart

Note:

1. If the directory specified by log_errors exists or does not have permissions, the error will still be output to the browser

2. The Centos user who writes the error log to the log_errors file is apache (not an apache server, but a user of Centos), so pay attention to the permissions of the apache user.
