PHP Telegram Bot VS PHPMailer

I was looking into he code of the PHP telegram bot for some troubleshooting. While looking at the Command.php, I noticed the class Command has several calls to $this->getMessage(), but it has no declaration for the function, nor inherits from any other class. Can anyone tell me what am I missing here? Here's a link to the file on github: https://github.com/php-telegram-bot/core/blob/master/src/Commands/Command.php

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.
