PHPdisk如何开发打印Json
include '../includes/commons.inc.php';define('P_W', 1);
include '../plugins/api/pw_api/class_json.php';
$arr = array ('a'=>1,'b'=>2,'c'=>3,'d'=>4,'e'=>5);
$json = new Services_JSON(true);
echo $json->json_encode($arr);
使用以上代码出错，请高人帮忙, 小弟不甚感激 你的代码应该正确呀 本帖最后由 JohnceCena2012 于 2012-10-10 17:29 编辑
