Yii数据读取与跳转参数传递用法实例分析

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：

<?php
var_dump($toop);
var_dump($var1);
var_dump($var2);
?>
