Getting information from nested arrays php - php

Question

I am making calls to an API
I have the response as an associative array so that I can use:
$field = $response['nameOfKey'];
However, some of the values for keys are themselves arrays like the following:
{
"Title": "Mr",
"Forenames": "Steve",
"Surname": "Williams",
"CountryOfBirth": 1,
"EmailAddress": "john.doe#email.com",
"EmailType": "Personal",
"BirthDate": "\/Date(632880000000)\/",
"Suffix": null,
"NationalInsuranceNumber": null,
"PrimaryAddress": {
"Address1": "Flat 1",
"Address2": "Oxford Street",
"City": "London",
"County": "London",
"Postcode": "L12456",
"Country": 1
},
"AdditionalAddresses": [
{
"Address1": null,
"Address2": null,
"City": null,
"County": null,
"Postcode": null,
"Country": 0,
"AddressType": 0
}
],
"PrimaryTelephone": {
"Number": "123456789",
"DialingCode": 1,
"TelephoneType": 1
},
"AdditionalTelephone": [
{
"Number": "223456789",
"DialingCode": 2,
"TelephoneType": 2
}
],
"BankAccount": {
"AccountName": "John Doe Account",
"AccountNumber": "123456789",
"SortCode": "123456"
},
"PrimaryCitizenship": {
"CountryOfResidency": 1,
"TaxIdentificationNumber": "AB12CD34EF56"
},
"AdditionalCitizenship": [
{
"CountryOfResidency": 0,
"TaxIdentificationNumber": null
}
],
"ExternalCustomerId": "91",
"ExternalPlanId": "91",
"PlanType": 10
}
So at the moment to get Forename I can just do $forename = $decodedResponse["Forenames"]; but I'm quite baffled at trying to get values from the inner arrays.
I thought I could do something like this:
foreach($decodedResponse as $data)
{
foreach($data['TelephoneNumbers'] as $tel)
{
echo $tel['Number']; die();
}
}
Essentially loop through the original Associative array and then loop through a specific key to get its values.

Answer 1

Your should use foreach for following array items: AdditionalAddresses, AdditionalTelephone and AdditionalCitizenship. Otherwise just chain array keys. See examples:
$forename = $decodedResponse['Forenames'];
$address2 = $decodedResponse['PrimaryAddress']['Address2'];
foreach ($decodedResponse['AdditionalTelephone'] as $tel) {
echo $tel['Number'];
}
