Comments

avatarrizwan6feb over 10 years ago

This is a list of 10 commonly used regular expressions. Building a regular expression for email and url is never easy and they are never 100% correct. There is a trade-off between simplicity and efficiency/accuracy when working with complex regular expressions like this. So the regular expressions for email and URL validation presented here are tried to be as simple as possible and at the same time accurate and effienct as well. All these regular expressions are tested in PHP only (using preg_match).
