PHPMailer VS Slim

Then make a form and use PHPMailer.

PHPMailer, as the name suggests, is an email-sending tool for PHP. It offers a straightforward and reliable approach to sending email messages from PHP applications. Security remains a top priority for the PHPMailer creators. It is equipped with built-in support for SSL/TLS encryption, ensuring the protection of email messages against interception and tampering. Moreover, it implements safeguards against common email injection attacks, effectively countering header injection and body injection vulnerabilities.

Have you tried using PHPMailer? mail() really isn't great and ends up being a lot more difficult to use. Phpmailer uses (or can use) SMTP (like Outlook or whichever email app) and is better at HTML and attachments and all that.

I found I have good experiences with a real email address provided by my domain/web host, and then I use the PHPMailer Class to send the message with the appropriate headers and what not.

The easiest way to send e-mails (from a beginner POV) is PHPMailer connected to an existing and configured SMTP server. Does your school has one? If yes, you're all set.

Welcome to this tutorial on how to send emails using PHP! Communication is key, and emails are an essential part of keeping in touch with your users. In this article, we will walk through the process of sending emails using PHP and PHPMailer - a powerful library for sending emails in PHP. We'll also cover how to configure PHPMailer to use SMTP, which is the most common way of sending emails on the web.

Alternatively try using XOAUTH: https://github.com/PHPMailer/PHPMailer/blob/master/examples/gmail_xoauth.phps

In any case, I don't recommend using mail() anyway. It's a low level function, a PITA to work with and you need to understand some infrastructure stuff to make it reliable. A simple alternative is https://github.com/PHPMailer/PHPMailer.

Currently Laravel is the "go to" for new PHP applications to mostly developers today, if not, plain PHP, Slim, Symfony and other frameworks does the job, but for Wordpress, custom PHP boilerplates or/and outdated PHP patterns (aka, single ton) is what we have for work in mostly cases, if not, hacky ways to integrate frameworks as Laravel itself or parts of it to leverage a better code structure.

Slim is a micro PHP framework used for web development with 11.7k stars and 2k forks on GitHub. It has a simple and intuitive API development process. It is a micro-framework, meaning you only get a minimum of support for HTTP requests and forwarding requests to appropriate controllers. So the question is, why should you choose a micro-framework? Because it offers you flexibility and high extensibility.

Slim 4, a minimalistic PHP micro-framework, offers middleware support to easily add CORS headers. Middleware in Slim acts like a series of layers through which your app sends a request. One such layer can be responsible for adding CORS headers.

SlimPHP 3 Skeleton app shows this as well: https://github.com/slimphp/Slim-Skeleton/blob/3.1.8/public/index.php

How hard did you look? There are plenty out there. FastRoute, Phroute, based on FastRoute, with basic middleware, League/Route - routing with middleware, using FastRoute, PSR 7 & 15, Slim Framework, at it's core, it like League/Route, etc. None of these require a full framework to use.

You can have the container call in a config folder with a file called dependencies or how ever you want. A few existing examples of this is here - Slim calls this app/dependencies in this skeleton project and Odan's Skeleton has this as config/container in their project.

Maybe use this if you don't like to dive into bigger frameworks: https://www.slimframework.com/
