本文實例講述了Yii數據讀取與跳轉參數傳遞用法。分享給大家供大家參考，具體如下：
|
1
2
3
4
5
6
7
8
9
10
11
12
|
$toop=array('id'=>'aaaa','name'=>'bbbb','nickname'=>'ccccc','phone'=>'ddddd','status'=>'eeeeee','mytest'=>$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的結果是：
|
1
2
3
4
5
6
7
8
9
10
11
12
13
14

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的結果：
|
1
2
3
4
5
6
7
8
9
10
11
12
13
14

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() 與 $dataReader->readAll() 不能同時使用 當$dataReader->read()讀完之后$dataReader->readAll()讀取的為空，反之一樣。
通過render傳遞的參數可以這樣調用：
|
1
2
3
4
5
|
<?phpvar_dump($toop);var_dump($var1);var_dump($var2);?> |
希望本文所述對大家基于Yii框架的PHP程序設計有所幫助。
