How To Validate Check Email Address is Correct In Forms When Submit PHP by webmaster

one of the best way to communicate with visitors and user is to provide a form. One of the most popular forms is the contact us forms. One of the essential fields to ask a user is for their email address. However, there are many people who just put garbage and not a real email address and you end up with spam or fake people's email address.

One way to confirm that users put a valid email address is with javascript, in my example if the user does not enter a vallid email address, they will received a popup window telling them that the email address they provided is not correct and to try again.
