Yii数据读取与跳转参数传递

$toop=array("id"=>"aaaa","name"=>"bbbb","nickname"=>"ccccc","phone"=>"ddddd","status"=>"eeeeee","mytest"=>$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" =>  "1" (length=1)
  "username" =>  "test1" (length=5)
  "password" =>  "pass1" (length=5)
  "email" =>  "test1@example.com" (length=17)

array (size=4)
  "id" =>  "2" (length=1)
  "username" =>  "test2" (length=5)
  "password" =>  "pass2" (length=5)
  "email" =>  "test2@example.com" (length=17)

array (size=4)
  "id" =>  "3" (length=1)
  "username" =>  "test3" (length=5)
  "password" =>  "pass3" (length=5)
  "email" =>  "test3@example.com" (length=17)

$rows的结果：
array (size=21)
  0 => 
    array (size=4)
      "id" =>  "1" (length=1)
      "username" =>  "test1" (length=5)
      "password" =>  "pass1" (length=5)
      "email" =>  "test1@example.com" (length=17)
  1 => 
    array (size=4)
      "id" =>  "2" (length=1)
      "username" =>  "test2" (length=5)
      "password" =>  "pass2" (length=5)
      "email" =>  "test2@example.com" (length=17)
  2 => 
    array (size=4)
      "id" =>  "3" (length=1)
      "username" =>  "test3" (length=5)
      "password" =>  "pass3" (length=5)
      "email" =>  "test3@example.com" (length=17)
  3 => 
    array (size=4)
      "id" =>  "4" (length=1)
      "username" =>  "test4" (length=5)
      "password" =>  "pass4" (length=5)
      "email" =>  "test4@example.com" (length=17)
$dataReader->read() 与 $dataReader->readAll() 不能同时使用 当$dataReader->read()读完之后

$dataReader->readAll()读取的为空，反之一样。
通过render传递的参数可以这样调用：
<?php
var_dump($toop);
var_dump($var1);
var_dump($var2);
?>
