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，因为它找不到类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或php5enmod中启用memcached扩展，具体取决于您的PHP版本。

在PHP 5.4.0中引入了

php5enmod，因此如果您使用的是旧版本的PHP，则需要手动编辑php.ini。

我刚刚升级了模块，然后又重新启动了所有服务。

未找到“Memcached”类但已安装在symfony2项目中
