DevShed has finished off their series looking at sending MIME emails with PHP in this new tutorial, moving the current code from the previous parts up to a fully PHP5 state.

While this mailer class can be used with small PHP applications, it lacks some important features related specifically to its object model, since it was built in PHP 4 from the very beginning.

They review the PHP4 version of the script first then move on to the process of porting it to a more standardized PHP5 structure and code.

DevShed continues its look at sending MIME emails with PHP in the fourth part of the series - a method for sending HTML in the message.

In this article, I'm going to show you how to provide the MIME mailer class with the ability to send email messages in HTML format. This will greatly extend its functionality, so don't miss this tutorial.

They start by reviewing the class they've created so far, including an example of its use. From there they modify it slightly to make it easy to embed the HTML content into the email by adding the addHTML and buildHTMLPart methods.

Continuing on in their look at sending MIME emails with PHP, DevShed has posted a better way for you to determine the correct MIME type of the file you're wanting to send (third part of the series).

I demonstrated how to build a modular MIME mailer class in PHP 4; it was provided with the capacity to send messages in plain text, and to work with different types of file attachments. This class implements a private method, called "getMimeTypes()," which, as its name would suggest, comes in handy for determining the correct MIME type of a given file. [...] However, the logic implemented by this method is rather primitive and can definitely be improved.

They start with a review of the previous code (PHP4) and show how to get the correct mime type of the file based on the extension mapped to an array of types.

On the Techfounder blog (from Eran Galperin) there's a quick tutorial about using the Zend_Mail component of the Zend Framework to send both normal, plain-text emails and ones with MIME attachments.

Using PHP's built in function (aptly named mail() ) is relatively straightforward - until you need slightly more advanced features, such as adding and encoding email headers or sending multiple mails efficiently. Fortunately, the Zend Framework comes with a very capable mail component called Zend_Mail.

He shows how to send a simple email, do something a bit more complex with a custom SMTP server, read messages from a remote POP3 email box and how to attach a binary file/message.

DevShed has posted the second part of their series looking at handling MIME attachments in PHP generated emails today. This time they focus on the modification of their PHP4 class to make sending the emails easy.

In this second tutorial of the series, I'm going to teach you how to improve the initial structure of the MIME mailer class developed in the first article by giving it the ability to work directly with attachments. Sounds fairly interesting, right? Then don't waste any more time in preliminaries and begin reading this article now!

They refresh you on the code from the former tutorial and show you how to modify it to work with more than just the simple plain-text attachment like before (with binary information, things like JPEGs, PDFs and other text formats like XML and HTML).

In this new tutorial on DevShed Alejandro Gervasio explains how to send emails from PHP with MIME payloads attached.

One of the most common tasks that a PHP programmer has to tackle is the development of applications that send MIME email in one form or another. In simple terms, MIME email consists of an extension of traditional email technology and comes in handy for sending email messages in fancy HTML and handling file attachments in a wide variety of formats.

In this first part of the series he just lays the groundwork - creating the mailer class they'll use for the series and using it to send a sample email (a basic message with a plain text MIME block).

DevShed has continued their series (here's part one) looking at the use of file uploading in your PHP scripts. They build on that foundation and add in some more useful features this time:

The initial script in the first tutorial of this series lacked some important features, such as the implementation of an effective error handling module and the ability to check the MIME type and size of the file being uploaded. In this second installment of the series, I'm going to improve the logic of the script from the first tutorial to provide it with the capacity to retrieve useful information concerning the entire file uploading process.

They look back at the previous tutorial to remind you of some of the concepts and then move on to show you how to get information about the file (like the MIME type, name and size of the uploaded file). The last page is just the full source code for the cut and pasters out there.

This article outlines the design of a PHP class for sending email with attachments. Everything you need to do this is supplied by the core PHP system, so nothing additional (such as non-bundled extensions) should be needed save for the required set up and connection between PHP and a SMTP mail package such as Sendmail or Postfix.

For details on setting up Sendmail and PHP, read through the appropriate section of the PHP manual. If you are already using the mail() function in PHP, you are ready to go right now.

They start off simple, creating the basic framework of the mailer class - to, from, subject, etc. From there, they build the header creation function to input the right information. Then, it's on to the heart of the matter - the "add attachment" function, and the "determine mime type" function". From there, the rest is simple...
