Validating email address in php

Furthermore, it's asynchronous nature offers both parties the freedom of participating at a time most convenient to their time schedule.

Given such qualities, it isn't a surprise that email has become a defacto tool of business for communicating with its clientele.

These days, users are expected to supply a valid email for just about everything, provided in exchange for the privilege of downloading software, learning more about the latest sales, and even for simply offering a comment to a favorite blogger's most recent entry.

For many users, admittedly myself included at times, the constant address beggaring has resulted in the prompt insertion of nonsensical, whimsical addresses such as "[email protected]", "23424!

I'll then conclude the tutorial by assembling both processes, and offering a few examples.

Not taking the time to properly verify user input in this regards is a detriment to not only the organization, but also the user who has shelled out time and perhaps money for your service!

The only way to do so is to ensure that the supplied address conforms to the Internet message format rules as set forth by RFC 2822.

Because reading an RFC is about as entertaining as a root canal, I'll offer a very broad summary of the rules here: Because of the innumerable syntactical variations which could arise as a result of these rules, we'll need to devise a regular expression capable of accounting for all possibilities.

In this article, I'll show you how to use the PHP scripting language to aid in the validation of email addresses on not only the level of syntactical correctness, but also of actual existence on the destination domain!

These easily implementable procedures will go a very long way towards eliminating future asdf's, blah's, and other invalid entries from your user database.

Our "validate email address" tool is 100% free, superbly fast and very accurate and reliable.
