Well You Can Get The Last Id from the table .. Then After The Insertion Add The Last id To The Count of your array .. But you Will face a problem and that is if you have 2 or more users inserted some records into this table at the same time .. so you can use The Transaction
try{
DB::beginTransaction();
// 1- get the last id of your table ($lastIdBeforeInsertion)
// 2- insert your data
Model::insert($array);
// 3- Getting the last inserted ids
$insertedIds = [];
for($i=1; $i<=theCountOfTheArray; $i++)
array_push($insertedIds, $lastIdBeforeInsertion+$i);
});
DB::commit();
}catch(\Exception $e){
DB::rollback();
}
or
DB::transaction(function() {
// 1- get the last id of your table ($lastIdBeforeInsertion)
// 2- insert your data
Model::insert($array);
// 3- Getting the last inserted ids
$insertedIds = [];
for($i=1; $i<=theCountOfTheArray; $i++)
array_push($insertedIds, $lastIdBeforeInsertion+$i);
});

Very Useful Article About Database Transactions
Edit
You Can make a unique Column and Call it for Example unique_bulk_id
.. This will hold randomly generated string for the inserted data .. after the insertion you can get the inserted data by This unique_bulk_id
.
