对象和数组的相互转化 php

class Test{
public $uname="aaaa";
public $email="aa@bb.com";

function tt()
{
echo 'this is tt';
}
}

$obj=new Test();
var_dump($obj);
$arr=get_object_vars($obj);
var_dump($arr);

echo "-----------------------------------\n";

$arr=['uname'=>'zhangsan','age'=>24];
var_dump((object)$arr);

object(Test)#1 (2) {
["uname"]=>
string(4) "aaaa"
["email"]=>
string(9) "aa@bb.com"
}
array(2) {
["uname"]=>
string(4) "aaaa"
["email"]=>
string(9) "aa@bb.com"
}
-----------------------------------
object(stdClass)#2 (2) {
["uname"]=>
string(8) "zhangsan"
["age"]=>
int(24)
}
