php email check

[perezf]

Is there a way in php to check if a email is valid,

I want to run a script that will check all of my emails in a file

so that way i dont get any bounce backs from non existent emails.

Well you can check for a valid email format, not sure on checking if it is a real email account. I guess that's up to the truthfulness of users. Search google for "PHP regex email validation"

I agree with ProjectFear. (as far as I know)

 

The best thing you can do to is to create email verification.

I'm not aware of a way to validate email existence, and if it exists, it must be a bit complicated. What I know, is a way of checking if the mail domain has mx records. Normally, as suggested previously you must run a regular expression to validate the email format. Consider this code:

 

<?php
$email = '[email protected]';
list($name, $domain) = explode('@', $email); //will explode the '@' to get two variables for the domain and name
if(checkdnsrr($domain, 'MX')){ //will check the dns of the domain for any MX records. you can discard the second parameter as the default is 'MX' but i wrote it for you to understand it
    echo 'Your email is valid.';
} else{
    echo 'Sorry, email invalid.';
}
?>

 

Unfortunately (or not) you can't use this function in windows platforms, but maybe a command such as "nslookup" can be used in the same way. Hope someone can give you a better method.
