[英]Php json_encode array and object array
I need to create a json with this format:我需要使用以下格式创建 json:
{
"reservs": [
{
"ResId": "58",
"time": "2020-05-15 19:41:50",
"boxEntering": null,
"boxClosing": null,
"active": "1",
"UserId": "29",
"BoxId": "4",
"boxPlace": null,
"box": {
"id": "4",
"Nom": "Hortillonages",
"Lat": "49.8953",
"Lng": "2.31034",
"place": "0",
"placeMax": "9"
}
}
]
}
in entries, a $header who check the user token(not use for my problem) $table the table returned from PDO::FETCHASSOC from sql SELECT request My php code: in entries, a $header who check the user token(not use for my problem) $table the table returned from PDO::FETCHASSOC from sql SELECT request My php code:

foreach ($table as $item) {
$box = array(
"id" => $item["id"],
"Nom" => $item["Nom"],
"Lat" => $item["Lat"],
"Lng" => $item["Lng"],
"place" => $item["place"],
"placeMax" => $item["placeMax"]
);
$reserv = array(
"ResId" => $item["ResId"],
"time" => $item["time"],
"boxEntering" => $item["boxEntering"],
"boxClosing" => $item["boxClosing"],
"active" => $item["active"],
"UserId" => $item["UserId"],
"BoxId" => $item["BoxId"],
"boxPlace" => $item["boxPlace"],
);
$reserv["box"] = $box;
array_merge($final,$reserv);
}
$arr = array("reservs" => $table);
$header->tokenJson($arr);
echo json_encode($arr);
}
I have this result我有这个结果
{"reservs": [
{
"ResId": "58",
"time": "2020-05-15 19:41:50",
"boxEntering": null,
"boxClosing": null,
"active": "1",
"UserId": "29",
"BoxId": "4",
"boxPlace": null,
"id": "4",
"Nom": "Hortillonages",
"Lat": "49.8953",
"Lng": "2.31034",
"place": "0",
"placeMax": "9",
"QRID": "",
"boxToken": ""
}]
}
I think the Json format eror is in the array_merge function.我认为 Json 格式错误在 array_merge function 中。 What add array function can I use to not remove the Box object我可以使用什么添加数组 function 来不删除框 object
Your problem is that you are not assigning the return of array_merge
and using the wrong variable $table
.您的问题是您没有分配array_merge
的返回并使用错误的变量$table
。 Just dynamically append to $final
:只是动态 append 到$final
:
foreach ($table as $item) {
// this all appears good
//
$reserv["box"] = $box;
$final[] = $reserv; // append to $final
}
$arr = array("reservs" => $final); // use $final
$header->tokenJson($arr);
echo json_encode($arr);
Merge the new $reserv
into $final
and assign it to $final
, then use $final
.将新的$reserv
合并到$final
并将其分配给$final
,然后使用$final
。
Try this one试试这个
function generateJson($table, headerChecker $header){
$final = array();
foreach ($table as $item) {
$box = array(
"id" => $item["id"],
"Nom" => $item["Nom"],
"Lat" => $item["Lat"],
"Lng" => $item["Lng"],
"place" => $item["place"],
"placeMax" => $item["placeMax"]
);
$reserv = array(
"ResId" => $item["ResId"],
"time" => $item["time"],
"boxEntering" => $item["boxEntering"],
"boxClosing" => $item["boxClosing"],
"active" => $item["active"],
"UserId" => $item["UserId"],
"BoxId" => $item["BoxId"],
"boxPlace" => $item["boxPlace"],
);
$reserv["box"] = $box;
$final[] = $reserv;
}
$arr = array("reservs" => $final);
$header->tokenJson($arr);
echo json_encode($arr);
}
