Validating an email address in php
Most of them are far too simple and ill-equipped to adequately deal with something as complex as an email address.While searching Google for terms such as “PHP validate email regex example”, I noticed that about 60-70% of the listed results were utter mush.We're doing the same, combining two different methods we've seen.A regular expression to match most email addresses, exotic ones would likely be missed.Another popular approach is to not validate email addresses at all.Because even the regex behind filter_var has its limitations, a lot of people are of the opinion that you should validate via a link that is sent out to the user’s email.Example of a correctly formatted email address but still wrong: [email protected][VALID format but does not exist] Above case specifically happens when you take important customer email on phone and you type in the wrong email.So is there a QUICK solution to really check the email without sending a test message to the user? 1) the 550 response indicates that the email address is not valid and you have caught a valid but wrong email address.
Seems like everyone and their brother has published one of these.
We have all been doing email address validation for a very long time to make sure that the email is correctly formatted.
