Difference Between php_admin_value[memory_limit] and php.ini memory_limit
Solution 1
There is no difference. There are different ways to set the same PHP configuration parameter.
It's useful - for example - if you have a generic php.ini which gets loaded in all PHP-FPM pools, but in one of them you want to override a certain value - like memory_limit
See http://php.net/manual/en/configuration.changes.php
Solution 2
One difference between memory_limit = 256M
in php.ini and php_admin_value[memory_limit] = 32M
in pool.d/www.conf is that you can use ini_set('memory_limit','512M')
to override the setting in php.ini but you can't override values set with php_admin_value
.
Use php_value[memory_limit] = 32M
if you want to allow it to be overridden. (php_value
vs php_admin_value
)

I have Nginx + php-fpm + Mysql. With the php memory settings, I always set this in php.ini like this:
memory_limit = 256M
Now, I bumped into another similar looking setting in
pool.d/www.conf
file like this:;php_admin_value[memory_limit] = 32M
My questions:
Although the doc says what that does, I couldnt read anywhere on what's the difference between memory_limit setting in
php.ini
and thephp_admin_value[memory_limit]
inwww.conf
?Do I need to set both or setting both makes it redundant?
Under what scenario do I need to specify the limit in
php_admin_value[memory_limit]
instead of adding it tomemory_limit
inphp.ini
?Can someone clear my confusion please?

Neel over 9 yearsThanks. So just having it in php.ini should be good enough then.
