復制代碼 代碼如下:

<?php
class myClass {
public $item1 = 1;
public $item2 = '中文';
function to_json() {
//url編碼,避免json_encode將中文轉為unicode
$this->item2 = urlencode($this->item2);
$str_json = json_encode($this);
//url解碼,轉完json后將各屬性返回,確保對象屬性不變
$this->item2 = urldecode($this->item2);
return urldecode($str_json);
}
}
$c = new myClass();
echo json_encode($c);
echo '<br/>';
echo $c->to_json();
echo '<br/>';
echo json_encode($c);
echo '<br/>';
echo json_encode('胥');
?>

復制代碼 代碼如下:

{"item1":1,"item2":"/u4e2d/u6587"}
{"item1":1,"item2":"中文"}
{"item1":1,"item2":"/u4e2d/u6587"}
"/u80e5"
