How to check that Email ID we are enterning in the register form is a valid one or not?


Valid means not according to regular expressions ?

For example if an entering a email like dsfgdsfgdhfg@sfgsadf.com (This email id should not be a valid one ) Where as, the email id like ram.hategals@gmail.com should be a valid one?


Thanks

Re : Forms

There are two methods that you can use in order to achieve your aim and see that an email address is valid.

The first method is to send an email to that address and ask the person to click a link to validate their email. Clearly if they click the link to validate the email address works.

The other method is to see if the domain name is a valid mail server, rather than the email address itself being valid, using a function called checkdnsrr.

Search php.net for more details on that.
