create array using two foreach - php

Question

I hope you guys can help me here, because I guess my code is not made correctly.
I have 2 mysql tables:
table: checks
+-----------+-------------+------------+
| id | name | host |
+-----------+-------------+------------+
| 1 | demo 1 | 1.1.1.1 |
+-----------+-------------+------------+
| 2 | demo 2 | 1.1.1.2 |
+-----------+-------------+------------+
| 3 | demo 3 | 1.1.1.3 |
+-----------+-------------+------------+
table: checks_history
+-----------+-------------+------------+------------+
| id | check_id | status | timestamp |
+-----------+-------------+------------+------------+
| 1 | 1 | 0 | 3451245 |
+-----------+-------------+------------+------------+
| 2 | 1 | 0 | 3451245 |
+-----------+-------------+------------+------------+
| 3 | 2 | 0 | 3451245 |
+-----------+-------------+------------+------------+
| 4 | 1 | 1 | 3451245 |
+-----------+-------------+------------+------------+
| 5 | 2 | 0 | 3451245 |
+-----------+-------------+------------+------------+
I want create a json file per id (table: checks) with this structure:
{
"info": { // Associated to table "checks"
"id": "1",
"name": "Demo 1",
"host": "1.1.1.1"
},
"data": { // associated to table check_history according with the id on table check
"1": { // associated to Column "id" on table checks_history
"status": "0",
"timestamp": "3451245"
},
"2": {
"status": "0",
"timestamp": "3451245"
},
"4": {
"status": "1",
"timestamp": "3451245"
}
}
}
There is my code PHP:
$info = array();
$history = array();
$incidents = $database->select("app_checks","*", false);
foreach ($incidents as $key => $value) {
$id = $value['id'];
$name = $value['name'];
$host = $value['host'];
$check_history = $database->select("app_checks_history", "*", [ "checkid" => $id, "ORDER" => ['id' => 'DESC'], "LIMIT" => 30 ]);
foreach ($check_history as $k => $v) {
$history = array(
$v['id'] => array(
'timestamp' => $v['timestamp'],
'status' => $v['status']
)
);
}
$info = array(
'info'=> array(
'id'=> $id,
'name'=> $name,
'host'=> $host
),
'data' => $history
);
$json_data = json_encode($info, JSON_PRETTY_PRINT);
$fileName = 'json/server_'.$id.'.json';
file_put_contents($fileName, $json_data);
}
When I try run the code, im getting the first value on "data" instead all loop:
{
"info": {
"id": "1",
"name": "Demo 1",
"host": "1.1.1.1"
},
"data": {
"1": {
"status": "0",
"timestamp": "3451245"
}
}
}
I searched in the forum and I did not found any similar issue related to my code.
I appreciate any help here.
Thanks in advance.

Well, I don't know PHP; however, I believe if you get your data model right, it should get you there. I would have my data model something like below in C#, an instance of Check class represent a check as per your table, serialize and save each instance in its own JSON file.
namespace Stackoverflow
{
using System;
using System.Collections.Generic;
using System.Globalization;
using Newtonsoft.Json;
using Newtonsoft.Json.Converters;
public partial class Check
{
[JsonProperty("info")]
public Info Info { get; set; }
[JsonProperty("data")]
public Dictionary<string, History> Data { get; set; }
}
public partial class History
{
[JsonProperty("status")]
[JsonConverter(typeof(ParseStringConverter))]
public long Status { get; set; }
[JsonProperty("timestamp")]
[JsonConverter(typeof(ParseStringConverter))]
public long Timestamp { get; set; }
}
public partial class Info
{
[JsonProperty("id")]
[JsonConverter(typeof(ParseStringConverter))]
public long Id { get; set; }
[JsonProperty("name")]
public string Name { get; set; }
[JsonProperty("host")]
public string Host { get; set; }
}
}
