I have the json array below and im trying to access the ProductResults bit.
I want the output to be somthing like this:
Term: 47, Type:HP, Payment: 229.4
Term: 47, Type:PCP, Payment: 172.23
Term: 60, Type:PCP, Payment: 186.82
But im struggeling to even access other parts of the array.
PHP:
$json = json_decode($resp, true);
foreach ($json['VehicleResults'] as $item)
{
$data = $item['FinanceProductResults'];
$v0 = $data['Term'];
echo $v0;
}
JSON:
{
"VehicleResults": [{
"Id": "0",
"FinanceProductResults": [{
"Term": 47,
"AnnualMileage": 6000,
"Deposits": 1000,
"ProductResults": [{
"Key": "HP",
"Payment": 229.4
}, {
"Key": "PCP",
"Payment": 172.23
}]
}, {
"Term": 60,
"AnnualMileage": 6000,
"Deposits": 1000,
"ProductResults": [{
"Key": "HP",
"Payment": 186.82
}]
}]
}]
}

The FinanceProductResults is also an array so it needs to be accessed also as an array. Like you have accessed VehicleResults and same goes for ProductResults. So your code should look something like this.
$json = json_decode($resp, true);
foreach ($json['VehicleResults'] as $item)
{
$dataItems = $item['FinanceProductResults'];
foreach ($dataItems as $data) {
$v0 = $data['Term'];
foreach ($data['ProductResults'] as $productResult) {
$type = $productResult['Key'];
$payment = $productResult['Payment'];
echo "Term: $v0, Type: $type, Payment: $payment";
}
}
}
