Save json data from input into database - php

Question

I get the json data using cURL as an input:
curl -H "Content-Type: application/json" -X GET http://localhost:8000/jsontest --data-binary #test.json
It is simple json with couple of fields:
{
"id": "12345",
"blockId": "9000",
"spot": {
"id": "7890",
"length": 23,
"name": "test",
"country": "de"
},
"channel": "tv:rtl.de",
"startTimestamp": "1323872435345",
"endTimestamp": "13243498394384329"
}
And this is my code for getting the data and storing in database:
public function test()
{
$string = file_get_contents('php://input');
$json_a = json_decode($string, true);
foreach ($json_a as $json => $test) {
$tvib = new TVIB;
$tvib->spotid = $test["spot"]["id"];
$tvib->name = $test["spot"]["name"];
$tvib->channel = $test["channel"];
$tvib->start = $test["startTimestamp"];
$tvib->end = $test["endTimestamp"];
$tvib->save();
}
var_dump($json_a);
}
When I run cURL request I get this error and a lot of html and js code:
ErrorException: Illegal string offset 'spot' in file TestController.php on line 18 ($tvib->spotid = $test["spot"]["id"];)
If I run this locally like this:
$string = file_get_contents('test.json');
everything works fine. But there is obviously problem with php input.
Any suggestions?
PS I use Laravel 5.5

not need foreach. so change code to :
public function test()
{
$string = file_get_contents('php://input');
$json_a = json_decode($string, true);
//foreach ($json_a as $json => $test) {
$tvib = new TVIB;
$tvib->spotid = $json_a["spot"]["id"];
$tvib->name = $json_a["spot"]["name"];
$tvib->channel = $json_a["channel"];
$tvib->start = $json_a["startTimestamp"];
$tvib->end = $json_a["endTimestamp"];
$tvib->save();
//}
var_dump($json_a);
}
