php 5.6中的memory_limit是否有任何值范围限制?

we have a UAT environment running with nginx and php-fpm. I was trying to increase the memory_limit to 2GB by changing the php.ini, .htaccess

After restarting the nginx and php-fpm, checked the phpinfo() and seeing that those changes are not taking affect on the environment.

May I know the reason for this?

better puts the configs here,as I tested,it is all ok,when I set the limit 2G,it displays 2G when echo info,restart the php service required
