我已經創建了一個php腳本，並用java撿起它，但我很難將它轉換爲我可以使用的格式。android解析使用php生成的JSON
PHP
<?php
//PDO is a extension which defines a lightweight, consistent interface for accessing databases in PHP.
$db=new PDO('mysql:dbname=mydb;host=localhost;','root','');
//here prepare the query for analyzing, prepared statements use less resources and thus run faster
$row=$db->prepare('select * from drinks');
$row->execute();//execute the query
$json_data=array();//create the array
foreach($row as $rec)//foreach loop
{
$json_array['drinks_id']=$rec['drinks_id'];
$json_array['drink_name']=$rec['drink_name'];
$json_array['Description']=$rec['Description'];
//here pushing the values in to an array
array_push($json_data,$json_array);
}
//built in PHP function to encode the data in to JSON format
//print_r($json_array);
echo json_encode($json_data,JSON_FORCE_OBJECT);
?>
JSON樣品（每行是accumative，而不是下一個certian標籤名稱爲）在Android中

},

"Description":"Beer"
},

登錄貓的樣品（僅一行是否打印？）
E/Menu: parseJson2: Value {"drinks_id":"1","drink_name":"Uprising Treason West Coast IPA","Description":"Beer"} at 0 of type org.json.JSONObject cannot be converted to JSONArray
你沒有'JSONArray'，你有一個'JSONObject' 。如果你改變你的JSON以''''''開始和結束，並且你移除了''0「，''1」'等等，我相信你的代碼應該可以工作 – 0xDEADC0DE
