How install apcu as php7 extension on debian

Question

I have seen this tutorial for ubuntu. http://thereluctantdeveloper.com/2015/12/quick-and-dirty-php-70-set-up-on-ubuntu-1404-with-apcu

It\'s not clear for me after st

Answer 1

Run :

sudo apt-get install php7.0-dev
pecl channel-update pecl.php.net
pecl install apcu

Do not immediately add extension=apcu.so on php.ini without checking. extension=apcu.so should automatically get added on /etc/php/7.0/cli/conf.d/20-apcu.ini. You can run php -i | grep app to check or cat /etc/php/7.0/cli/conf.d/20-apcu.ini. If you load twice, you'll get :

PHP Warning:  Module 'apcu' already loaded in Unknown on line 0

This message is probably kept for older system :

install ok: channel://pecl.php.net/apcu-5.1.5
configuration option "php_ini" is not set to php.ini location
You should add "extension=apcu.so" to php.ini

I can not comment on the existing answer (point is less than 50). I got that PHP error, then found that file.
