What should I do if the php error log does not take effect?

Remember a pitfall where PHP error_log output log does not take effect

At first I wanted to use error_log() to output logs in the project, and enable the following configuration in php.ini:

log_errors = On
error_log = /mnt/hgfs/workspace/php-error.log

Then use error_log() to print the log in the project and find that php-error.log has no content

Use phpinfo() to view the configuration

Found that the configuration in php.ini did not take effect. Edit /etc/php-fpm.d/www.conf

Comment out these two lines and restart php-fpm. , check again that phpinfo

# has become the value we configured, call error_log() again, and find that it can be correctly output to the file, because php_admin_value will overwrite the value in php.ini value.
