[英]How to split and change the json format
我正在使用slimphp v2,并且具有以下功能
function gt($user) {
$sql = "select id, id as categoryId, mobile, task from actions where status=0";
try {
$db = newDB($user);
$stmt = $db - > prepare($sql);
$stmt - > execute();
$gs = $stmt - > fetchAll(PDO::FETCH_OBJ);
if ($gs) {
$db = null;
echo json_encode($gs, JSON_UNESCAPED_UNICODE);
} else {
echo "Not Found";
}
} catch (PDOException $e) {
echo '{"error":{"text":'.$e - > getMessage().
'}}';
}
}
默认的json输出如下所示:
[{
"id": "1",
"categoryId": "1",
"mobile": "111",
"task": "test"
},
{
"id": "2",
"categoryId": "2",
"mobile": "222",
"task": "test2"
}]
和我想做的输出。 我需要生成一个ID:1_(id)然后像这样格式化它
[{
id: "1",
task: "test",
}, {
ID: "1_1", //generate this, add 1_id
categoryId: "1",
mobile: "00000",
}, {
id: "2",
task: "test2",
}, {
ID: "1_2", //generate this, add 1_id
categoryId: "2",
mobile: "11111"
}];
可能吗? 谢谢
我不确定这是否完全符合您的要求,但是您可以通过将原始JSON转换为关联数组,然后使用Foreach()
循环将每次迭代的数据重组为新的assoc数组,来获得所需的JSON输出。 之后,您可以使用json_encode()
将其转换回JSON。
码:
$json = '[{
"id": "1",
"categoryId": "1",
"mobile": "111",
"task": "test"
},
{
"id": "2",
"categoryId": "2",
"mobile": "222",
"task": "test2"
}]';
$jsonArr = json_decode($json, TRUE);
$newArr = [];
foreach ($jsonArr as $v) {
$newArr[] = ['id:'=>$v['id'], 'task:' => $v['task']];
$newArr[] = ['ID:'=>'1_' . $v['id'], 'categoryId' => $v['categoryId'], 'mobile'=>$v['mobile']];
}
$newJson = json_encode($newArr);
var_dump($newJson);
输出:
[{
"id:": "1",
"task:": "test"
}, {
"ID:": "1_1",
"categoryId": "1",
"mobile": "111"
}, {
"id:": "2",
"task:": "test2"
}, {
"ID:": "1_2",
"categoryId": "2",
"mobile": "222"
}]

如注释中所述,您将SQL数组作为对象输出。 我已经使用PDO::FETCH_ASSOC
将Fetch设置为关联数组输出,并更改了foreach()
循环以引用assoc数组$gs
。 这应该可以,但是如果不行,则使用var_dump($gs)
再次输出$gs
的结果。 如果需要,您仍然需要编码为JSON,但是此行已被注释掉。
function gt($user) {
$sql = "select id, id as categoryId, mobile, task from actions where status=0";
try {
$db = newDB($user);
$stmt = $db->prepare($sql);
$stmt->execute();
$gs = $stmt->fetchAll(PDO::FETCH_ASSOC); //Fetch as Associative Array
if ($gs) {
$db = null;
$newArr = [];
foreach ($gs as $v) { //$gs Array should still work with foreach loop
$newArr[] = ['id:'=>$v['id'], 'task:' => $v['task']];
$newArr[] = ['ID:'=>'1_' . $v['id'], 'categoryId' => $v['categoryId'], 'mobile'=>$v['mobile']];
}
//$newJson = json_encode($newArr); //JSON encode here if you want it converted to JSON.
} else {
echo "Not Found";
}
} catch(PDOException $e) {
//error_log($e->getMessage(), 3, '/var/tmp/php.log');
echo '{"error":{"text":'. $e->getMessage() .'}}';
}
}
