Swift is a fully OOP Library for sending e-mails from PHP websites and applications. It does not rely on PHP’s native mail() function which is known for using high server resources when sending multiple emails. Instead, Swift communicates directly with an SMTP server or a MTA binary to send mail quickly and efficiently.
Swift is comparable to PHPMailer except that it implements an extremely flexible and innovative plugin system meaning you can get the most out of sending emails from your PHP applications. The interface for Swift is both tighter and more intuitive.
I started developing Swift because I moderate a popular PHP forum and it’s clear from some of the posts we see that PHP’s native mail() function just doesn’t quite cut it among developers unless you know a lot about how to build emails and you only need to send one message. The only other popular alternative was PHPMailer which is ok, but is no longer in active development, limited in support, lacking in modern features such as TLS and difficult to interface with. So I wrote Swift initially for the communtity at the PHP Developer’s Network Forums and have decided to release it now under the LGPL. Enjoy!
