| Perl and PHP Regular Expressions | |
| PHP regexes are based on the PCRE (Perl-Compatible Regular Expressions), so any regexp that works for one should be compatible with the other or any other language that makes use of the PCRE format. Here are some commonly needed regular expressions for both PHP and Perl. Each regex will be in string format and will include delimiters. | |
| All Major Credit Cards | |
| This regular expression will validate all major credit cards: American Express (Amex), Discover, Mastercard, and Visa. | |

Note: The original guide, linked from the PWA Starter Kit docs provides step-by-step instructions on how to configure "Firebase Hosting + Firebase Functions" to allow deployment of the PWA Starter Kit, using a manual approach. This guide attempts to correct, simplify, and/or update the original by making use of the Firebase CLI.
If you already have some Firebase knowledge, you might want to checkout the Firebase branch on the PWA Starter Kit repo, that already contains the files and folders completed by following the [original guide](https://gist.github.com/Dabolus/314bd939959ebe68f57f1dc
