I am trying to create an array which shows the layout of an array.

This would be the input:

    $array = [

        'company' => [

            'contacts' => [

                'first_names',

                'last_name',

                'emails',

                'phones' => [

                    'test'

                ]

            ],

            'addresses' => [

                'postal_code'

            ],

        ]

    ];

And this is what I am trying to get the output to look like:

    $array = [

        'company.contacts.phones'

        'company.addresses'

    ];

I have been trying to work this out for hours but haven't manages to come up with a solution. It needs to work with any layout/depth of input array.

> 'Google',_ 'location' => 'Mountain View',_ 'employees' => 10000,_ 'revenue' => 1000000000,_ ];_And this would be the desired output:_ $mappedArray = [_ 'company',_ 'location',_ 'employees',_ 'revenue',_ ];_I am trying to achieve this by using the array_keys() function in PHP, but I am not sure how to map the keys to the desired output array.
