Extract a string from an object inside an array: PHP

Question

I'm writing a PHP plugin and need to extract a string from an object which is inside an array.

var_dump($data)

outputs:

array(1) { 
    [0]=> object(stdClass)#380 (53) { 
        ["id"]=> string(1) "2" 
        ["firstname"]=> string(6) "John" 
        ["lastname"]=> string(6) "Doe" 
        ["email"]=> string(31) "johndoe@email.com" 
    } 
}

I want to return:

johndoe@mail.com

My research has turned up functions such as unserialize, array_map, array_slice, and array_column, but I haven't found the right function or combination of functions that work together (nor do I understand them enough) to just return a simple string from an object inside an array. Can anyone provide me with some guidance?

Edit: This isn't the same question as the one referenced as "the exact same question." The other one asks simply how to access an array (answer: $array[0]), and my question asked how to access an object INSIDE an array (answer: $array[0]->text).

Programming works by composition. If you know how to access an array element, and you know how to access an object property, just put them together to access a property of an array element. — Barmar, Apr 18 '17 at 16:27
I don't really get the question. Is something going to dynamic, such as the array structure or object key names? — Álvaro González, Apr 18 '17 at 16:35

For example:

$data[0]->firstname

Maybe:

$arr = get_object_vars($data[0]);
$arr['firstname'];

Example:

$obj = (object) array('x' => 'foo');
$arr = [$obj];

print($arr[0]->x);

You will get: foo
