PHPMailer is an email sending class specially used in PHP language. It is very powerful and enriches the single mail() function of PHP itself. Supports SMTP and more even attachments.

PHPMailer complies with the LGPL license and can be downloaded for free. The current version is PHPMailer v2.2.1, which was updated on November 16, 2007.
Download address: http://phpmailer.codeworxtech.com/index.php?pg=sf&p=dl
Note: When downloading, the suffixes are .tar.gz and .zip. In fact, they contain The files are all the same, but the compression format is different. .tar.gz has been double-compressed and the file is smaller. WinRAR software can decompress these two formats correctly.

◆How to use:

☆ Previous note: After decompression, there will be an examples folder in the file package, which contains "pop3_before_smtp_test.php" and "test1. php" two files. The first file teaches basic usage (see below), while "test1.php" mainly introduces some new features, which are detailed in "index.html" in the same folder. , and another file "contents.html" is the email content, which can be replaced with an email template in the future to increase the standardization and enrichment of the email.

☆Basic method: pop3_before_smtp_test.php
