未定义的类常量'MYSQL_ATTR_INIT_COMMAND'原则

Question

我正在使用ZendServer 6.2.0 php 5.4和apache2

我正在尝试通过以下this教程配置doctrine，当我运行该命令时：./ netndor / bin / doctrine-module orm：validate-schema我收到错误：

第19行的var / www / CommunicationApp / config / autoload / global.php中未定义的类常量'MYSQL_ATTR_INIT_COMMAND'

我已经取消注释/usr/local/zend/etc/php.ini中的extension = php_pdo_mysql.dll

我尝试安装php5-mysql，但它取代了zendserver。
