json的键名为数字时的调用方式(示例代码)_php技巧
对于键名为数字或者非正常变量字符时（如有空格），必须使用obj[xx]方式获取值。
//声明json数据
$array = array('result'=>array("90"=>"90队列","status"=>"成功"));
$json = json_encode($array);
$array1 = array("90"=>"90队列","status"=>"成功");
$json1 = json_encode($array1);
$phpjson = json_decode($json1,true);//第二个参数是true，表示把json数据转换为数组
//对于json键名是数字时，只能用数组方式处理$phpjson['90'];
?>
