PHP数组传递给JavaScript以及json_encode的gbk中文乱码的解决

/* 处理json_encode中文乱码 */

class myClass {
public $item1 = 1;
public $item2 = '中文';
function to_json() {
//url编码,避免json_encode将中文转为unicode
$this->item2 = urlencode($this->item2);
$str_json = json_encode($this);
//url解码,转完json后将各属性返回,确保对象属性不变
$this->item2 = urldecode($this->item2);
return urldecode($str_json);
}
}

echo json_encode($c);
echo '

echo $c->to_json();
echo '

echo json_encode($c);
echo '

程序输出结果：

{"item1":1,"item2":"u4e2du6587"}
{"item1":1,"item2":"中文"}
{"item1":1,"item2":"u4e2du6587"}
"u80e5"
