Email sending techniques in PHP

With the development of Internet technology, email is becoming more and more important in people's daily life and work. In website development, sending emails is a common need, and PHP, as a popular programming language, provides many email sending techniques to meet the needs of developers.

This article will introduce email sending techniques in PHP, including email protocols, email libraries, email templates, etc., to help developers better understand and use PHP to send emails.

Email Protocol

Before sending an email, we need to understand some basic knowledge of the email protocol. SMTP (Simple Mail Transfer Protocol) is a standard protocol for sending emails. In PHP, we can use SMTP protocol to send emails.

Mail library

PHP provides some commonly used mail libraries that can help us easily complete the task of sending emails.

PHPMailer is one of the most popular mail libraries, with over 9,000 stars on GitHub. It provides flexible configuration options, supports multiple email protocols, and can easily add attachments and email content in HTML format.

Another commonly used email library is Swift Mailer, which also provides rich configuration options and supports multiple email protocols.

Email Template

Email templates can help us better control the format and content of emails when sending them. In PHP, we can use a template engine to generate email templates.

Twig is a popular PHP template engine that is scalable and flexible and can easily generate email content in HTML format.

Mail Service Provider

In addition to using the SMTP protocol to send emails, we can also use email service providers to send emails. Email service providers can usually provide more stable and reliable email services, and can support more functions, such as email tracking and statistics.

Commonly used email service providers include SendGrid, Mailgun and Mandrill. These email service providers usually provide API interfaces and documentation to help developers easily integrate email sending functions.

Finally, we need to pay attention to some precautions when sending emails:

1. When sending emails, you need to ensure the correctness of the email address to avoid failure to send the email due to an incorrect address.

2. Avoid using spam keywords to ensure that the email will not be intercepted as spam.

3. Avoid sending too many emails. Sending a large number of emails in a short period of time may be considered spam.
