php loop adds extra data to database - php

Question

I have loop to store my data and it multiple the rows.
example
I have 3 rows with value of test1 and I need to add this rows to become 5
so I have 3 rows already
I add number in input field 2
I loop this 2 number and create new rows
previously 3 rows + 2 new rows = 5 rows in total
but currently I am getting 9 rows.
Code
foreach($request->input('barcodes') as $bb)
{
for ($i = 0; $i < $request->input('nonuiqueAmount'); ++$i) {
$barcode = new Barcode;
$barcode->product_id = $product->id;
$barcode->returned = false;
$barcode->serial_number = $bb['serial_number'];
$barcode->save();
}
}
In case you need a full code with logic here I shared it for you.
Any idea why I get more than my desire rows?

Solved
Thanks to u_mulder suggestion here is how I solved my issue
foreach($request->input('barcodes') as $bb)
{
$bbb = $bb['serial_number']; // added to get single serial number
}
for ($i = 0; $i < $request->input('nonuiqueAmount'); ++$i) {
$barcode = new Barcode;
$barcode->product_id = $product->id;
$barcode->returned = false;
$barcode->serial_number = $bbb; // changed
if($barcode->save()) {
$user = Auth::user();
$outlets = $user->outlets;
foreach($outlets as $outlet) {
DB::table('outlet_products')->insert([
'outlet_id' => $outlet->id,
'barcode_id' => $barcode->id,
'created_at' => now(),
'updated_at' => now(),
]);
}
}
}
