PHP Question

Nginx or PHP FPM ignores memory_limit in php.ini

Server info: Ubuntu Server, Nginx, PHP FPM

in

/etc/php5/fpm/php.ini
I have:
memory_limit = 512M

in
/etc/php5/fpm/php-fpm.conf
I have:
php_admin_value[memory_limit] = 512M


php_value[memory_limit] = 512M


My phpinfo looks like:



PHP Version 5.3.10-1ubuntu3.6

The problem is when i change
upload_max_filesize
size then the
phpinfo
will show the new value, but when I change
memory_limit
then nothing changes.
I guess in somewhere the memory_limit is overwrited. But i cannot find it.
Can anyone help me?

Answer

You can take Nginx out of the picture, it just passes the request on, it's in php-fpm running your php code.

you might check your suhosin settings, suhosin.memory_limit.

when you see your phpinfo output there should be 2 columns, master and local for memory_limit, what do these each show?

128M is the default for memory_limit in php 5.3
