How to get attribute from a collection, with multiple objects inside of an array in Laravel?

Question

I have a collection that contains an array with 2 objects in it. I'm trying to get the email attribute, right now there are only 2 objects, but there could be 100 objects, so I'm not sure if I need a loop or if I need to use array_merge, or something. I've attached a screenshot of the data, I'm not showing the attributes, but just know that one of them is email. I'm die/dumping a variable called $tokens.

In the end, it should return a list of emails, for example:

john.doe@email.com
jane@email.com
thomas.brown@email.com

And I need this logic in the controller, not in the view (.blade), because I'm trying to save this data in a csv file, using fputcsv, that's the main objective and idea here.

Thank you to @jagcweb for the inspiration, his code/answer just needed a couple of tweaks. The following works and does what I was trying to do:

$emails_array = array();
for($i=0; $i <= sizeof($tokens)-1; $i++) {
    array_push($emails_array, $tokens[$i]["email"]);
}

Now the $emails_array contains an array with both emails in it.
