Yii 配置中设置mysql端口号其实很简单，请看下面的代码

'db' => array(
'class' => 'CDbConnection',
'connectionString' => 'mysql:host=localhost;dbname=phpac',
'username' => 'root',
'password' => '123456',
),
这是修改后的Yii的mysql配置代码

'db' => array(
'class' => 'CDbConnection',
'connectionString' => 'mysql:host=localhost;port=13306;dbname=phpac',
'username' => 'root',
'password' => '123456',
),
我们只要在connectionString中插入了port=13306这样的参数设置即可… 各个参数之间以;隔开…
