本文实例讲述了Yii数据读取与跳转参数传递用法。分享给大家供大家参考，具体如下：

$toop=array('id'=>'aaaa','name'=>'bbbb','nickname'=>'ccccc','phone'=>'ddddd','status'=>'eeeeee','mytest'=>$te);

$test='hello world!';

$te="\$this->test='qweqw'";

$conn=Yii::app()->db;

$sql="select * from tbl_user";

$command=$conn->createCommand($sql);

$dataReader=$command->query();

//$rows=$dataReader->readAll();

while(($row=$dataReader->read())!==false) {

var_dump($row);

}

$this->render('index',array('toop'=>$toop,'var1'=>$test,'var2'=>$te));

$row的结果是：

array (size=4)

'id' => string '1' (length=1)

'username' => string 'test1' (length=5)

'password' => string 'pass1' (length=5)

'email' => string 'test1@example.com' (length=17)

array (size=4)

'id' => string '2' (length=1)

'username' => string 'test2' (length=5)

'password' => string 'pass2' (length=5)

'email' => string 'test2@example.com' (length=17)

array (size=4)

'id' => string '3' (length=1)

'username' => string 'test3' (length=5)

'password' => string 'pass3' (length=5)

'email' => string 'test3@example.com' (length=17)

$rows的结果：

array (size=21)

0 =>

array (size=4)

'id' => string '1' (length=1)

'username' => string 'test1' (length=5)

'password' => string 'pass1' (length=5)

'email' => string 'test1@example.com' (length=17)

1 =>

array (size=4)

'id' => string '2' (length=1)

'username' => string 'test2' (length=5)

'password' => string 'pass2' (length=5)

'email' => string 'test2@example.com' (length=17)

2 =>

array (size=4)

'id' => string '3' (length=1)

'username' => string 'test3' (length=5)

'password' => string 'pass3' (length=5)

'email' => string 'test3@example.com' (length=17)

3 =>

array (size=4)

'id' => string '4' (length=1)

'username' => string 'test4' (length=5)

'password' => string 'pass4' (length=5)

'email' => string 'test4@example.com' (length=17)

$dataReader->read() 与 $dataReader->readAll() 不能同时使用 当$dataReader->read()读完之后$dataReader->readAll()读取的为空，反之一样。

通过render传递的参数可以这样调用：

var_dump($toop);

var_dump($var1);

var_dump($var2);

?>

希望本文所述对大家基于Yii框架的PHP程序设计有所帮助。
