Pushing values into multidimensional array with PHP

Question

I'm using CakePHP and retrieve user info, make a calculation, and then I'd like to add that calculation into the array per user

After looking up a user, this is the structure of the array

print_r($user_info);

Array
(
    [0] => Array
        (
            [User] => Array
                (
                    [id] => 1
                    [email] => [email protected]
                    [website] => www.admin.com

                )

        )

)

Now I'm trying to add a 'num_payments' key for this particular user in a loop

array_push($user_info[$i]['User'],array('num_payments' => $customer_payments[$i]['num_payments']));

Here's the resulting array

Array
(
    [0] => Array
        (
            [User] => Array
                (
                    [id] => 1
                    [email] => [email protected]
                    [website] => www.admin.com
                    [0] => Array
                        (
                            [num_payments] => 1
                        )

                )

        )

)

How can I get it into this structure?

Array
(
    [0] => Array
        (
            [User] => Array
                (
                    [id] => 1
                    [email] => [email protected]
                    [website] => www.admin.com
                    [num_payments] => 1
                )

        )

)

without array_push:

$user_info[$i]['User']['num_payments'] = $customer_payments[$i]['num_payments'];

So just loop through the values?

user1443519 Over a year ago

Wow, that was painfully obvious. Time to step away from the keyboard. Thanks!

$user_info[$i]['User']['num_payments'] = $customer_payments[$i]['num_payments'];

It sounds like you should add a join to your query to pull in the data combined with the user data. Then you can use the Hash::combine method to merge the data into the array it belongs to.

However, if you are just running a loop on the data, you should be able to add it like:

foreach ($user_info as $i -> $data) {
  $user_info[$i]['User']['num_payments'] = $customer_payments[$i]['num_payments'];
}

This is assuming that $i corresponds to the same record in both arrays.

If $i in $customer_payments corresponds to the User.id, then it will require that you do this:

foreach ($user_info as $i -> $data) {
  $user_info[$i]['User']['num_payments'] = $customer_payments[$user_info[$i]['User']['id']]['num_payments'];
}
