CDbConnection无法打开数据库连接:在Yii中找不到驱动程序 [英] CDbConnection failed to open the DB connection: could not find driver in Yii

问题描述

在yii框架中尝试与mysql连接时显示

while trying to connect with mysql in yii framework it shows

"CDbConnection无法打开数据库连接:找不到驱动程序"错误

"CDbConnection failed to open the DB connection: could not find driver " error

php代码:

     'db'=>array(
        'class' => 'CDbConnection',
        'connectionString' => 'mysql:host=localhost:3306;dbname=testdrive',
        'emulatePrepare' => true,
        'username' => 'root',
        'password' => 'root',
        'charset' => 'utf8',
    ), 

我的php驱动程序已启用，但显示相同的错误

my php drivers are already enabled , but it shows the same error

我正在为此使用Zend Studio，Zend服务器

Im using zend studio, zend server for this

我该如何解决?

推荐答案

您应检查的内容

首先，您应该检查phpinfo()中是否安装了pdo_drivers.

First you should check phpinfo() for the pdo_drivers installed.

如果您使用IIS服务器，则应检查是否已安装php扩展名.

if u use IIS server , you should check php extensions installed or not.

检查php.ini是否提供了extensions_dir

check php.ini for extensions_dir is properly given

检查您在php中的ext文件夹是否包含pdo_mysql dlls

check you ext folder in php contains pdo_mysql dlls

有时会由于安装zend服务器而出现问题.您应该使用php扩展名检查zend服务器是否正确

Some times the problem may occur due to zend server installation .You should check zend server is properly using the php extensions

之后，使用以下功能检查简单的php-mysql连接

After that check simple php-mysql connection using the following functions

mysql_connect('localhost:3306','root','root');
mysql_select_db('testdrive');

如果可以，请使用Yii，Slim，Zend php-mysql连接

If it works then go with Yii, Slim, Zend php-mysql connections
