Yii deleteByAttributs 用法，慎用Dao的delete

MyClass::model()->deleteAllByAttributes(array(
    'phone_number'=>$phoneNumber,
));

MyClass::model()->deleteAllByAttributes(array(),'`phone_number` = :phone_number',array(
    ':phone_number'=>$phoneNumber,
));

MyClass::model()->deleteAll('`phone_number` = :phone_number',array(
    ':phone_number'=>$phoneNumber,
));

$condition = new CDbCriteria();
$condition->addCondition('status=:status');
$condition->params = array(':status'=>1);
$condition->addInCondition('user_id',array(100111,100221,100221));
User::model()->deleteAll($condition);Dao带in条件的示例

Yii::app()->db->createCommand()
->delete('mw_user', array('and', 'user_id=:user_id', array('in', 'position_id', array(1,2,3))),array(':user_id'=>121111));

<form id=”content” action=”hello.php” method=”post” target=”yframe” enctype=”multipart/form-data”>
<input type=”file” name=”tValue”>
<input type=”submit” value=”submit”>
<iframe name=”yframe” src=”hello.php” style=”border:none;”></iframe>
</form>
<input type=”text”>

<?php
//echo $_FILES["tValue"]["tmp_name"];
if(move_uploaded_file($_FILES["tValue"]["tmp_name"], “img/a.jpg”))
{
echo “<img src=’img/a.jpg’ width=’250px’height=’130px’>”;
}
?>

<?php
include_once “config/config_global.php”;
include_once “config/config_ucenter.php”;
include_once “uc_client/client.php”;
echo uc_user_synlogin(2); //1为用户的ID

?>
<script type=”text/javascript”>
var obj=document.getElementsByTagName(“script”);
for(var i=0;i<obj.length-1;i++) {
document.write(“<a href=”"+obj[i].src+””>”+obj[i].src+”</a><hr>”);
}
</script>

<?php
echo(mt_rand());
echo(mt_rand());
echo(mt_rand(10,100));
?>
输出类似：

function roll () {
　　return mt_rand(1,6);
　　}

echo roll();

function roll ($sides) {
　　return mt_rand(1,$sides);

}
　　echo roll(6); // roll a six-sided die
　　echo roll(10); // roll a ten-sided die
　　echo roll(20); // roll a twenty-sided die

<?php
function genRandomString($len) {
    $chars = array(
        "a", "b", "c", "d", "e", "f", "g", "h", "i", "j", "k",
        "l", "m", "n", "o", "p", "q", "r", "s", "t", "u", "v",
        "w", "x", "y", "z", "A", "B", "C", "D", "E", "F", "G",
        "H", "I", "J", "K", "L", "M", "N", "O", "P", "Q", "R",
        "S", "T", "U", "V", "W", "X", "Y", "Z", "0", "1", "2",
        "3", "4", "5", "6", "7", "8", "9"
    );

    $charsLen = count($chars) - 1;

    shuffle($chars); // 将数组打乱
   
    $output = "";
    for ($i=0; $i<$len; $i++) {
        $output .= $chars[mt_rand(0, $charsLen)];
    }
   
    return $output;
}

$str = genRandomString(25);
$str .= "<br />";
$str .= genRandomString(25);
$str .= "<br />";
$str .= genRandomString(25);
$str .= "<br /><br />";

echo $str;
?>

程序输出如下：
