I have a CSV file like this 我有这样的CSV文件

Joseph,Dean,2025550194
Elbert,Valdez,2025550148
Using this csv-to-json.php from GitHub I get output like this 使用来自GitHub的csv-to-json.php我得到这样的输出
[{
"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 这几乎是我想要的-但是不是
"phone": "2025550194"
I need 我需要
"phone": [{
"type": "phone",
"number": "2025550194"
}]
How do I correct this? 我该如何纠正?
If you get the JSON string, then you would of course first convert it to an array with: 如果您获得JSON字符串,那么您当然会首先将其转换为以下数组:
$arr = json_decode($json, true);
But probably you already have the array. 但是可能您已经有了该数组。 You then apply this loop to it: 然后将以下循环应用于它:
foreach($arr as &$row) {
if (isset($row['phone'])) { // only when there is a phone number:
$row['phone'] = [[ "type" => "phone", "number" => $row['phone'] ]];
}
}
You can change the csv-to-json.php code with following and you got the output that you want :- 您可以使用以下命令将csv-to-json.php代码更改为您想要的输出:-
Option 1 :- 选项1 :-
// Bring it all together
for ($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 :- 选项2:-
$json_response = [{
"first_name": "Joseph",
"last_name": "Dean",

}, {
"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;
