CDbConnection failed to open the DB connection: could not find driver in Yii
mysql, php, yii, yii-cactiverecord, zend-studio
Solution
Things you should check
First you should check phpinfo() for the pdo_drivers installed.
if u use IIS server , you should check php extensions installed or not.
check php.ini for extensions_dir is properly given
check you ext folder in php contains pdo_mysql dlls
Some times the problem may occur due to zend server installation .You should check zend server is properly using the php extensions
After that check simple php-mysql connection using the following functions
mysql_connect('localhost:3306','root','root');
mysql_select_db('testdrive');
If it works then go with Yii, Slim, Zend php-mysql connections
Problem
while trying to connect with mysql in yii framework it shows "CDbConnection failed to open the DB connection: could not find driver " error php code : ``` 'db'=>array( 'class' => 'CDbConnection', 'connectionString' => 'mysql:host=localhost:3306;dbname=testdrive', 'emulatePrepare' => true, 'username' => 'root', 'password' => 'root', 'charset' => 'utf8', ), ``` my php drivers are already enabled , but it shows the same error Im using zend studio, zend server for this how could i fix this?
