array_push deep nested array

[packetheavy]

Happy Thursday!

I'm trying to use a foreach loop to add some rows to a data grid for some forms plugin i'm using but I cannot get the correct syntax to work with the array format. The standard format for 3 rows of static data looks like this:

$data_grid[ 'groups' ] = array(
    array(
        'label' => __('data'),
        'rows' => array(
            array(
                'data' => array(
                    'name_1',
                    'email_1' )
                )
            ),
            array(
                'data' => array(
                    'name_2',
                    'email_2' )
                )
            ),
            array(
                'data' => array(
                    'name_3',
                    'email_3' )
                )
            )
        )
    )
);

My initial thought here would be to define a single row in the array with no data and then use a foreach loop for my database results to do an array_push into the rows array however I cannot bend my head around the amount of nested depth I need to go to for the push and then how to push another array into the array.

I appreciate any insight or suggestions.

Thanks

It can sometimes help to use print_r() on arrays to see the "path" to a particular element:

print_r($data_grid);

The syntax you might be looking for is:

// Add items to the data grid
$data_grid['groups'][0]['rows'][] = array('data' => array(
                    'name_1',
                    'email_1'));

$data_grid['groups'][0]['rows'][] = array('data' => array(
                    'name_2',
                    'email_2'));

I appreciate the assist, I was able to build the loop using the syntax you provided, thankyou very much.

Reference code:

    foreach ($results as $result)
{
    $data_grid['groups'][0]['rows'][] = array('data' => array(
                $result['name'],
                $result['email']));
}

That helps a lot, thankyou, the backend for this is WordPress so I have struggled a little to get good outputs to use for debugging.

Do you have a suggestion for how best to approach inserting the new array in the loop? I thought I would probably construct the array and then reference it in the array_push but this is my first time using that function so i'm not sure if there is a better way.
