Send Emails with Attachments via PHP

The free library Swift Mailer allows software programmers to send emails message with attachments from inside their PHP applications. You need to instantiate the Swift_Attachment object and use the attach method to include your attachments. Apart from the file attachments, you can also embed images in the email message text. The library also fully supports the embedding of dynamically generated content without having an existing file available. You can just use one-liner code to embed already existing files or use URL.

Emails Encoding via PHP API

The Swift Mailer library makes it easy for software developers to add encoding capability to their PHP applications. The library has included support for encoding the body of the MIME part of the email message. It also allows encoding the binary attachments using base64. The text parts are encoded using quoted-printable which is a safe choice and most modern SMTP servers support it.

The library supports adding a customized header to an email message as well as modifying an existing one with ease. Modifying the existing header is a very difficult task as there is very little difference between the headers. The Swift Mailer library used different types of MIME headers which are categorized into more general groups, such as text headers, parameterized headers, date headers, ID headers, and path Headers.
