Fetching data from Json

I have a json object. I need to get the values after decoding the json object.

However, some values are blank at times. This brings an error to the way I am fetching.

Kindly see below and advice.

$json = '{
 "Customers": {
 "IdentityStrings": [
 {
 "UniqueSystemIdentifier": "202000000000007004",
 "MSISDN": "211920494162",
 "FirstName": "Donald",
 "MiddleName": {
 },
 "LastName": "Twesiga",
 "DateOfBirth": "2000-01-01",
 "DateIdentityActivated": "20170816153810",
 "DateIdentityRegistered": "20170816153448",
 "OperatorNameRegisteredBy": {
 },
 }
 ]
 },
}';

To get the values, I json decode and fetch as below.

$jsonData = json_decode($json);
 foreach ($jsonData->Customers->IdentityStrings[0] as $key => $value) {
 $UniqueSystemIdentifier = ($jsonData->Customers->IdentityStrings[0]->UniqueSystemIdentifier);
 $MSISDN = ($jsonData->Customers->IdentityStrings[0]->MSISDN);
 $FirstName = ($jsonData->Customers->IdentityStrings[0]->FirstName);
 $MiddleName = ($jsonData->Customers->IdentityStrings[0]->MiddleName);
 $LastName = $jsonData->Customers->IdentityStrings[0]->LastName;
 $DateOfBirth = $jsonData->Customers->IdentityStrings[0]->DateOfBirth;
 $OperatorNameRegisteredBy = $jsonData->Customers->IdentityStrings[0]->OperatorNameRegisteredBy;
 }

The problem comes when some are empty like in this case MiddleName and OperatorNameRegisteredBy.

How can I fetch in case they have values or not?

Thank you.

• @YvesLeBorg I think he only pasted partial Json, and forgot to remove the trailing commas.
