Class 'Memcached' 未找到但已安装在 symfony2 项目中

Question

我有一个 symfony2 项目，它使用 Memcached 来实现它的一些功能。现在整个应用程序都崩溃了，因为它找不到 class Memcached。

我安装了 memcached 和 php5-memcached。我错过了什么吗？

apt-get install memcached php5-memcached

Answer 1

您可能忘记在 php.ini 中或通过 php5enmod 启用 memcached 扩展，具体取决于您的 PHP 版本。

php5enmod 是在 PHP 5.4.0 中引入的，因此如果您有旧版本的 PHP，您需要手动编辑 php.ini。

我刚刚升级了模块，然后又重新启动了我的所有服务。
