How to send json data from url to database and update it - php

Question

Hy,
I just cant figure it out how to get this to work.
How do I post the home>name, home>score to the database (the same for away) and send the status, rounds and datetime to the database.
But if there is a change in the json url than update the database and if there is a new match insert it.
this all needs to be done automatically.

"home":{
"name":"Worst Players",
"url":"/counterstrike/teams/15191-worst-players",
"country":"Russian Federation",

},
"away":{

"url":"/counterstrike/teams/14464-team-empire",
"country":"Russian Federation",
"rank":40,
"score":2
},
"status":"Complete",
"type":"counterstrike",
"rounds":"Best of 3",
"valueBet":true,
"datetime":1462024800
},

"rank":39
},
"status":"Upcoming",
"type":"counterstrike",
"rounds":"Best of 3",
"valueBet":true,
"datetime":1462068000
}
]
I have tried this code
<?php
include("../../check.php");
$urljson = "http://localhost:5000/matches";
$json = file_get_contents($urljson);
$data = json_decode($json, TRUE);
$home = $data[0]['home'];
$away = $data[0]['away'];
$status = $data[0]['status'];
$type = $data[0]['rounds'];
$timestamp = $data[0]['datetime'];
foreach($data as $array) {
echo $home['name'];
echo '<br>';
echo $home['score'];
echo '<br>';
echo $away['name'];
echo '<br>';
echo $away['score'];
echo '<br>';
echo $status;
echo '<br>';
echo $type;
echo '<br>';
echo $timestamp;
echo '<br>';
echo '<br>';
}
?>
but this is what the webpage gave me (it showed mutiple times the same result)
ANOX
Notice: Undefined index: score in C:\xampp\htdocs\main\dashboard\backend\info.php on line 18
Worst Players
Notice: Undefined index: score in C:\xampp\htdocs\main\dashboard\backend\info.php on line 22
Upcoming
Best of 3
1462100400
I hope someone can help me with this beceause I am stuck for like 4 days now.

Answer 1

You get the same data all the time cause you are using the wrong variables inside the loop. Use the $array variable in your case:
foreach($data as $array) {
echo $array['name'];
echo '<br>';
echo $array['score'];
echo '<br>';
... etc.
}
Maybe it would be good to call the variable $row or $match instead of $array for better readability.
You get the "Notice: Undefined..." because there are some JSON nodes where there is no score. Check for score before using it with
if (isset($array['score'])) {
// use it inside if:
echo $array['score']
}
Here the corrected code:
<?php
include("../../check.php");
$urljson = "http://localhost:5000/matches";
$json = file_get_contents($urljson);
$data = json_decode($json, TRUE);
foreach($data as $match) {
echo $match['home']['name'];
echo '<br>';
if (isset($match['home']['score'])) {
echo $match['home']['score'];
echo '<br>';
}
echo $match['away']['name'];
echo '<br>';
if (isset($match['away']['score'])) {
echo $match['away']['score'];
echo '<br>';
}
echo $match['status'];
echo '<br>';
echo $match['rounds'];
echo '<br>';
echo $match['datetime'];
echo '<br>';
echo '<br>';
}
?>
