Question

我正在尝试生成一个包含多个json对象的json数组。下面是我输出的代码。

<?php

    include_once "/db_connect.php";
    $db = new DB_CONNECT();
    $head='0';
    if(empty($head)){

    for($head=1;$head<20;$head++){
    if(!empty($head)){

    $flatp=mysql_query("SELECT co.id,co.user_id,co.cat_id,co.flatP,hds.HeadName,co.offer_name,u.shop_name,co.cost FROM createdoffers co INNER JOIN categories ct ON ct.id=co.cat_id INNER JOIN 
            users u ON u.id=co.user_id INNER JOIN heads hds ON hds.id=ct.Head_id 
            WHERE ct.Head_id='$head' AND ct.id=co.cat_id AND co.user_id=u.id ORDER BY co.flatP DESC LIMIT 1");

        if (mysql_num_rows($flatp) >0) {
        $response["createdoffers"] = array();
        while ($row = mysql_fetch_array($flatp)) {
        $recp = array();

                $recp["HeadName"]= $row["HeadName"];
                $recp["offer_name1"]=$row["offer_name"];
                $recp["shop_name1"]=$row['shop_name'];
                $recp["cost1"]=$row['cost'];

            array_push($response["createdoffers"], $recp);

        }
        $object=array(array_filter((array)$response));  
        $res = json_encode($object);
         echo trim($res,'[]');
        }               

    }

    }
    }
    ?>

这是我的输出，它有不同的json对象和不同的json数组..

{＆＃34; createdoffers＆＃34;：[{＆＃34; HEADNAME＆＃34;：＆＃34;汽车摩托车＆＃34;＆＃34; offer_name1＆＃34;：＆＃34;平坦＆＃34; ，＆＃34; shop_name1＆＃34;：＆＃34;编码蜘蛛＆＃34;，＆＃34; cost1＆＃34;：＆＃34; 1300.00＆＃34;}]}

{＆＃34; createdoffers＆＃34;：[{＆＃34; HeadName＆＃34;：＆＃34; Computer and Electroincs＆＃34;，＆＃34; offer_name1＆＃34;：＆＃34;欢乐时光＆＃34;，＆＃34; shop_name1＆＃34;：＆＃34;编码蜘蛛＆＃34;，＆＃34; cost1＆＃34;：＆＃34; 17000.00＆＃34;}]}

{＆＃34; createdoffers＆＃34;：[{＆＃34; HeadName＆＃34;：＆＃34; Food and Dining＆＃34;，＆＃34; offer_name1＆＃34;：＆＃34; flat＆＃ 34;，＆＃34; shop_name1＆＃34;：＆＃34; codingspider＆＃34;＆＃34; COST1＆＃34;：＆＃34; 100.00＆＃34;}]}

我想要的是将所有这三个json对象生成为一个json数组。我无法在这找到什么错误..
