我想用php创建一个像下面这样的json对象。它将返回一个字符串作为结果sql查询的响应。
{"Orders":[
{"DeliveryId":"DeliveryId","CustomerName":"CustomerName","PhoneNumber":"PhoneNumber","Address":"Address"},
{"DeliveryId":"DeliveryId","CustomerName":"CustomerName","PhoneNumber":"PhoneNumber","Address":"Address"}
]
}
我的代码
<?php
mysql_connect("mysql12.000webhost.com","a4602996_longvan","longvan2012");
mysql_select_db("a4602996_lv");
$id=$_POST[user];
$sql=mysql_query("select * from testlongvan where Status = 'PACKED'" );
$json = array();
if(mysql_num_rows($sql)){
while($row=mysql_fetch_row($sql)){
$json['Orders'][]=$row;
}
}
//while($row=mysql_fetch_assoc($sql))
//$output[]=$row;
print(json_encode($json));
mysql_close();
?>
但是当使用我的代码时,结果不符合我的预期:
{ “订单”:[ [“longvan”,“10/12/2012”,“Be34433jh”,“Long Van”,“115 Pham Viet Chanh,quan Binh Thanh”,“http://longvansolution.tk/image/sample.jpg”,“压缩”, “0909056788”], [“takehi”,“24/12/2012”,“BF6464633”,“Vn-zoom”,“16 nguyen cuu van,quan binh thanh”,“http://longvansolution.tk/image/hoadon3.jpg”, “压缩”, “098897657”] ]}
你能帮助我吗?

您必须为每一行创建一个数组,以指定字段名称和值。
$json['Orders'][] = array('DeliveryId' => $row[0], 'CustomerName' => $row[1], ...);
如果表列名称正是您要在JSON中使用的名称,请使用mysqli_fetch_assoc()函数:
$rows = array();
while($r = mysqli_fetch_assoc($sql)) {
$rows[] = $r;
}
$data = array('Orders' => $rows);
print json_encode($data);
