【问题描述】：

我有以下为我生成数据的函数：

 function get_project_time() 
        $name;
        $desc;
        $values;
        $to;
        $from;
        $sql = $this->db->query("Select * from tbl_project")->result();
        foreach ($sql as $value) 

            $name = $value->project_name;
            $desc = $value->project_status;
            $start_date = $value->start_date;
            $end_date = $value->end_date;
            $unix_start_date = strtotime($start_date);
            $unix_end_date = strtotime($end_date);
            $to = "Date($unix_start_date)/";
            $from = "Date($unix_end_date)/";
            $e = new stdClass();
            $f = new stdClass();
            $e->name = $name;
            $e->desc = $desc;
            $f->to = $to;
            $f->from = $from;
            $e->values = array($f);

            echo json_encode(array($e));
        
    

json 输出格式如下：

["name":"e-Campus and eLearning Project","desc":"in_progress","values":["to":"\/Date(1473627600)\/","from":"\/Date(1480626000)\/"]]["name":"BloodLink Training Project","desc":"in_progress","values":["to":"\/Date(1474405200)\/","from":"\/Date(1475010000)\/"]]["name":"Test Project","desc":"","values":["to":"\/Date(1474405200)\/","from":"\/Date(1475182800)\/"]]

我想清理数据，以便得到这样的结果：

["name":"e-Campus and eLearning Project","desc":"in_progress","values":["to":"/Date(1473627600)/","from":"/Date(1480626000)/"]]["name":"BloodLink Training Project","desc":"in_progress","values":["to":"/Date(1474405200)/","from":"/Date(1475010000)/"]]["name":"Test Project","desc":"","values":["to":"/Date(1474405200)/","from":"/Date(1475182800)/"]]

请告知我如何清理 json 数据？

你做错了。您正在循环中执行echo json_encode(..)，因此您正在生成多个独立的 json 字符串。您需要在循环内构建一个数组/对象。您只需在构建完成时在流程结束时进行编码。

【参考方案1】：

大部分代码都是多余的/无用的。你可以为自己节省很多 类似这样的行数：

$sql = "SELECT project_name AS name, ... UNIX_TIMESTAMP(end_date) AS end_date etc...";

while($row = fetch()) 
   $array[] = $row;


echo json_encode($array);

构建一个对象，只是为了将它类型转换为一个数组，这完全是浪费和混乱。如果你想要一个数组，然后构建一个数组。完成“给我一个带有额外生菜的巨无霸”，然后将其转换为菲力鱼。
