Loop to get user data - php

Question

I can't put real code here because is very long and will be hard to
explain.
I have users table in database and I have data table in database too.
So, to get the user data I'll pass user_id as parameter. Like this:
public function get_user_data($user_id) {
}
But. I can only get 1 data per "request". (Keep reading)
public function user_data() {
$getUsers = $this->db->get('users');
foreach($getUsers->result_array() as $user)
{
$data = $this->get_user_data($user->ID);
var_dump($data); // Only return 1 data;
}
}
But, I guess that have an way to "bypass" this but I don't know. I'm having trouble thinking.
As I said, I want to "bypass" this, and be able to send multiple user IDs, my real function do not accept that by default and can't be changed.
Thanks in advance!

Answer 1

replace
foreach($getUsers->result_array() as $user)
{
$data = $this->get_user_data($user->ID);
var_dump($data); // Only return 1 data;
}
to this
foreach($getUsers->result_array() as $user)
{
$data[] = $this->get_user_data($user->ID);
}
var_dump($data);

If you are aiming at sending more data to the function, you always need to make signature change of your function as one of the below :
function get_user_data() {
$args = func_get_args();
/** now you can access these as $args[0], $args[1] **/
}
Or
function get_user_data(...$user_ids) {
/** now you can access these as $user_ids[0], $user_ids[1] **/
}
// Only higher version of PHP
But I am not sure how you will handle returning data.
EDIT: Yes, then in the function, you can collect data in array and return an array of data from function.

If you can change in your function from where to where_in I think you will get an easy solution.
public function get_user_data($user_ids)
{
// your db code
$this->db->where_in('ID',$user_ids); //replace where with where_in
}
public function user_data()
{
$getUsers = $this->db->get('users');
foreach($getUsers->result_array() as $user)
{
$user_ids[] = $user->ID;
}
$this->get_user_data($user_ids);
}
