Converting a JSON string to a JSON array - php

Question

I have a CSV file like this
first_name,last_name,phone
Joseph,Dean,2025550194
Elbert,Valdez,2025550148
Using this csv-to-json.php from GitHub I get output like this
[{
"first_name": "Joseph",
"last_name": "Dean",
"phone": "2025550194",
"id": 0
}, {
"first_name": "Elbert",
"last_name": "Valdez",
"phone": "2025550148",
"id": 1
}]
This is almost what I want - however instead of
"phone": "2025550194"
I need
"phone": [{
"type": "phone",
"number": "2025550194"
}]
How do I correct this?

Answer 1

If you get the JSON string, then you would of course first convert it to an array with:
$arr = json_decode($json, true);
But probably you already have the array. You then apply this loop to it:
foreach($arr as &$row) {
if (isset($row['phone'])) { // only when there is a phone number:
$row['phone'] = [[ "type" => "phone", "number" => $row['phone'] ]];
}
}
See it run on eval.in.

You can change the csv-to-json.php code with following and you got the output that you want :-
Option 1 :-
// Bring it all together
for ($j = 0; $j < $count; $j++) {
$d = array_combine($keys, $data[$j]);
if ($j == 'phone') {
$newArray[$j] = array('type' => $j, 'number' => $d);
} else {
$newArray[$j] = $d;
}
}
Option 2 :-
$json_response = [{
"first_name": "Joseph",
"last_name": "Dean",
"phone": "2025550194",
"id": 0
}, {
"first_name": "Elbert",
"last_name": "Valdez",
"phone": "2025550148",
"id": 1
}];
$result = json_decode($json_response);
$final_result = array();
foreach ($result as $row) {
$row['phone'] = array('type' => 'phone', 'number' => $row['phone']);
$final_result[] = $row;
}
echo json_encode($final_result);
It may help you.
