How to get values of multiple nested arrays in PHP? - php

Question

This is a shorter version of my question from How to get values only from a PHP array inside multiple nested Arrays without knowing value? so hoping someone can help.
MAIN ISSUE I don't know what to call to get things inside ARRAY
What I need is inside that Array of Extras. I've duplicated & modified everything I can to get these values but can't seem to figure it out. Any help is really appreciated.
The registration, milage, condition shown is the output of $autoshowroom_portfolio_specifications_arr
array (
'label' => __( 'Checkboxes field', 'progression-car-dealer' ),
'name' => 'pcd_checkboxes',
'display' => 'table',
'min' => '',
'max' => '',
'sub_fields' => array (
array (
'key' => 'field_52816dc9ffee11',
'label' => __( 'Checkboxes to Customize', 'progression-car-dealer' ),
'name' => 'pcd_checkboxes',
'type' => 'checkbox',
'instructions' => __( 'Selected fields will be used', 'progression-car-dealer' ),
'choices' => $choices,
'default_value' => '',
'layout' => 'horizontal',
)
),
