While processing forms email address validation plays an important. Proper email validation strengthen our contact list, ban spamming and protect us from robot form filling (Form AutoFill). Here we are going to design a regular expression pattern to validate email address. which will check to make sure an e-mail address is a valid address, and in proper format means containing an username, at sign (@), and valid hostname. For example, admin@samplehost.com is valid, but SPAM@badhost is invalid. Most of email service provides limit the use of literals for email address creation. Only letters (a-z,A-Z), numbers (0-9), hyphens (-), underscore (_) and periods (.) are allowed and no special characters are accepted. You can add or remove any literals to your regular expression.<<less

Why is that? Because the developer doesnt control it. You can write the best algorithm in the world, but still if it includes user input there is a place for mistakes. Even if we put some coplicated logic to prevent the input of wrong symbols, check the consistence of the data and do whatever possible to make sure that it is all OK, there is still possibility that the users enter the wrong number. Though all said, we must try to prevent the most of human errors and the best way to do this is by using Regular Expressions. Basicly Regular Expressions are used for string matches. They are based on search and pattern matching strings in text. A lot of books are written about them, there are even some programming languages designed especially for Regular Expressions.<<less
