I am running a Debain PHP5.4.4 and I want to install opcache.
I tried with :
pecl install opcache
pecl install ZendOpache-beta
Not good: "No releases available for package "
(Since server is in production I don't think it would be safe to install php5.5.)
pecl install zendopcache-7.0.5
source: https://pecl.php.net/package/ZendOpcache Don't forget activate it by adding extension to php.ini
