Array of values from the same radio button group - php

Question

I'm making a website in Laravel where user needs to enter his pseudonym, and on the settings page he can add multiple pseudonyms with jQuery. When he clicks the plus button, a text field, radio button and minus fields are added.
Radio buttons are there to mark one of those nicknames as default.
Image: screenshot of how the inputs look like
How do I pass an array of values out of those radio buttons? ie, if I selected 3rd out of 4 pseudonyms to be default:
{'0' => null, '1' => null, '2' => '1', '3'=> null}
So I can merge this array into pseudonyms array to be like:
{'0' => {'0' => 'John Doe', '1' => null},
'1' => {'0' => 'John Smith', '1' => null},
'2' => {'0' => 'John Wayne', '1' => '1'},
'3' => {'0' => 'John X', '1' => null}}
Finally, I would save it like this, or some other method that would also check if already existent and then update, but that's not important right now:
foreach($pseudonyms as $pseudonym)
$user->pseudonyms()->create(['name' => $pseudonym[0], 'status' => $pseudonym[1]]);
I'm probably just inexperienced and don't know some html/php basics that will let me do that, but what can I do :)
Anyway, here's the Blade part where inputs are:
<div class="input_fields_wrap">
<div class="row">
<div class="col-md-8">
{!! Form::text('pseudonyms[]', null,['class' => 'form-control']) !!}
</div>
<div class="col-md-2">
{!! Form::radio('default[]', 1, null,['class' => 'form-control']) !!}
</div>
<div class="col-md-2">
{!! Form::button('<i class="fa fa-plus" aria-hidden="true"></i>',['class'=>'btn btn-default add_field']) !!}
</div>
</div>
</div>
And here is the part of jQuery that appends the additional fields in .input_fields_wrap
$(document).ready(function() {
var max_fields = 5; //maximum input boxes allowed
var wrapper = $(".input_fields_wrap .row"); //Fields wrapper
var add_button = $(".add_field"); //Add button ID
var added_fields = 1; //initial text box count
$(add_button).click(function(e){ //on add input button click
e.preventDefault();
if(added_fields < max_fields){ //max input box allowed
$(wrapper).append('<div class="added"><div class="col-md-8 class1"><input type="text" name="pseudonyms[]" class="form-control"/></div>' +
'<div class="col-md-2 class2" ><input type="radio" name="default[]" value="1" class="form-control"/></div>' +
'<div class="col-md-2 class3" ><input type="button" value="-" class="remove_field btn btn-default add_field fa fa-minus"></div></div>'); //add input box
added_fields++; //text box increment
}
});
$(wrapper).on("click",".remove_field", function(e){ //user click on remove text
e.preventDefault();
$(this).closest('.added').remove();
added_fields--;
})
});
Thank you for your comments!

Of course, solution was working on something else, coming back and having an answer after 2 minutes thinking about it. Created new array with a key from the radio button's value, so I could merge it with the other array with
foreach($request->pseudonyms as $key => $value)
{
if(array_key_exists($key, $default))
{
$pseudonyms[$key] = array($value, $default[$key]);
} else {
$pseudonyms[$key] = array($value, null);
}
}
