访问数组内的数组

I'm working on my task right now, which accessing specific array when it is called by front end. My example data is like this

{
    "data": [
        {
            "name": "Jon Snow",
            "id": "01-0001",
        },
        {
            "name": "Robert Stark",
            "id": "01-0002"
        },
        {
            "name": "Sansa Stark",
            "id": "01-002333"
        },
        {
            "name": "Arya Stark",
            "id": "01-00012"
        },
        {
            "name": "Bran Stark",
            "id": "01-0003"
        },
         {
            "name": "Rickon Stark",
            "id": "01-0005"
        }

    ]
}

* In my front end I have this code *

 selectedEmployee: any=null;

    setActiveEmployee(employee: any) {
        this.selectedEmployee = employee;
        let myJSON = JSON.stringify(this.selectedEmployee);
        this.perEmpLateEarly();
    }

Whenever I choose the employee i get the id of that employee. So in this, if i choose "id": "01-0001" it will return the first array and it will keep the rest, and if I choose "id": "01-0002" it will return the second one and will keep the rest and so on. How can I do that in Php?

Thanks in advance

You will do a GET/POST HTTP request from frontend, which would look something like this in

your_backend_page.php?id=<ID HERE>

Then the "your_backend_page.php" would look like as follows:

$list = {  "data": [ { .... }, { ...   }] } // this is the array you have

$idFromFrontEnd = $_GET["id"];

foreach ($list["data"] as $item) {   // iterate over all items
    if ($item["id"] == $idFromFrontEnd) {   // check if id matches
       echo json_decode($item);     // if matches, print this item
    }

}

Please note this approach is okay if you have a small number of items. For a larger list, you might want to have a database, where you can use sql to select.
