change "0" to names in Json file - php

Question

I am using PHP array and outputing to JSON string. I want to convert "0" in the json format to lets say calling them "items". Since while importing this to oracle db it says expecting names instead of zero. When I change the index ( 0, 1, 2 ) to be called just items, it works normally.
Here is the PHP array, and I am outputting it as json.
$data = array(
'INDIVIDUAL_SALUTATION' => $salution,
'INDIVIDUAL_FIRST_NAME' => $firstname,
'INDIVIDUAL_LAST_NAME' => $lastname,
'GENDER' => $gender,
'DATE_OF_BIRTH' => $result['Birthday'],
'EMAIL_ID' => $result['Email'],
'MOBILE_NUMBER' =>$result['Phone'],
'MOBILE_COUNTRY_CODE' => substr($result['Phone'], 1, 3),
'OCCUPATION' => null,
'OCCUPATION_STATUS' => null,
'ADDRESS_LINE1' => $result['Address_street'],
'TOWN' => $result['Address_city'],
'POSTAL_CODE' => $result['Address_zip'],
'COUNTRY' => $result['country_name'],
'CUSTOMER_NUMBER' => $result['Owner'],
'POLICY_START_DATE' => $result['paid_thru_date'],
'POLICY_END_DATE' => $result['duedate'],
'LOAN_AGREEMENT_NUMBER' => $result['ORIG_ID'],
'REPAYABLE_AMOUNT' => $result['repayable_amount'],
'FINANCE_TERM_MONTHS' => $result['finance_term_months'],
'MONTHLY_INSTALLMENT' => $result['monthly_installment'],
'AMOUNT_INSURED' => $result['amount_insured'],
'CURRENCY_ID' => $result['Abbreviation']
);
$jsonArray[] = $data;
}
$mainInfo = array(
'SRC_NAME' => 'AEX',
"RUN_NUMBER" => 1,
"RUN_DATE" => date("Ymd"),
"RUN_NO_OF_RECORDS" => $arrayCount,
"YTD_NO_OF_RECORDS" => $arrayCount
);
$finalArray = array_merge($jsonArray , $mainInfo);
$this->output->set_content_type('application/json');
$this->output->set_output(json_encode($finalArray));
$this->output->set_content_type('application/json');
$this->output->set_output(json_encode($mainInfo));
Here is the output
{

},

}
What I am trying to do is make it look like instead of 0 have 'items' : {} and then move on, so I can import it to oracle.
How can I achieve this with php?

Answer 1

Don't use array_merge, put the array in an element of $mainInfo:
$mainInfo['items'] = $jsonArray;
$this->output->set_output(json_encode($mainInfo));

Answer 2

Create index variable and make it to zero
$index = 0
And change this $jsonArray[] = $data; to this $jsonArray['item' .$index++] = $data;
Hope that helps
