Ellipsis before parameter variable PHP Laravel

Was going through Laravel Illuminate core when I met this code..What’s does the ellipsis before parameter $guards mean?

public function handle($request,Closure $next,...$guards){

Using PHP and MySQL data to generate PDF letters like in MS Word mailmerge functionality - development

Using PHP and MySQL data to generate PDF letters like in MS Word mailmerge functionality I would really like to know if there is a way like MS Word mailmerge functionality that can be done using PHP and Mysql data. Like i have address data in MySQL (suppose 10 numbers) and through PHP i want to insert that address data in a pre-defined letter head area. And it will automatically generate 10 different letters with same content but different address in PDF. Can it be done? Any start up point will be helpful. As I am working on Laravel so any snippet of that sort will also be useful.

Here is live link – WORKS IN CHROME In Chrome it works, however, in Safari, FF, Edge, it does not. I referenced this suggested answer which suggests referencing the ID attribute, which I believe I am already doing: $scope.defaultFill = function (colors) { if (colors) { var defaultCol...
