php.ini 更新未反映在 phpinfo() output

Question

I am trying to update memory_limit in php.ini, but I don't see the value updated in phpinfo(). Here is the ini file path info from phpinfo():

Configuration File (php.ini) Path:  /etc
Loaded Configuration File:  /etc/php.ini 

Updated /etc/php.ini and then ran:

systemctl restart httpd

I tried updating other values in ini file to see if anything gets updated, but nothing does.

I am on an AWS EC2 linux instance with wordpress.

Many modern PHP installations run PHP-FPM by default, instead of as an Apache module mod_php. PHP-FPM is itself a separate service that needs to be restarted via your operating system's preferred method. eg

$ sudo systemctl restart php-fpm

You mentioned you already knew which php.ini to modify from the phpinfo() output. For future readers, the PHP-FPM service may use a different php.ini. Consult the output from phpinfo() when loaded via the web to find out which php.ini to modify.
