Validating an email addy

[tcorbeil]

And another..

 

I use:

 

if (!@file_get_contents($weblink)){

@header("Location: ".$_SERVER['HTTP_REFERER']);

}

 

where $weblink is equal to a website.. this is to validate a weblink..

 

What would I use to validate an email address?

 

Thanks.

www.php.net/ereg

 

view the user comments you will find a validation function there.

Found this code on the site:

 

On a small note to email checking:

Recently it is possible to register domains like www.k�che.de

 

This would also mean that the IsEMail() function from "php at easy2sync dot com" would report an email address like "contact@k�che.de" as false.

 

To correct this, use the function below:

 

function IsEMail($e)

{

    if(eregi("^[a-zA-Z0-9]+[_a-zA-Z0-9-]*

(\.[_a-z0-9-]+)*@[a-z������0-9]+

(-[a-z������0-9]+)*(\.[a-z������0-9-]+)*

(\.[a-z]{2,4})$", $e))

    {

        return TRUE;

    }

    return FALSE;

}

 

not sure if I'm implementing it correctly..

 

do i call as such?

 

$Email = [email protected]

IsEMail ($Email);

 

out of the function above, how would I come out with a marker variable such as $verify = It's good or $verify= It's bad...

Can anyone clarify?

 

Thanks.

Use This reg exp

 

if(preg_match("/^[a-zA-Z_]+(\w+)*((-\w+)|(\.\w+))*\@\w+((\.|-)\w+)*\.\w+$/i",$email){

          echo "valid email";

}

I have modified the code to this:

 

    if(eregi("/^[a-zA-Z_]+(\w+)*((-\w+)|(\.\w+))*\@\w+((\.|-)\w+)*\.\w+$/i", $Email))

    {

        return TRUE;

echo "1";}

 

I don't see the echo come up even though I know it is valid.. any other suggestions?

Once the return statement is executed, the function stops. Put the echo before the return.

Hi Ken.

 

I did exactly what you mentioned and it still does not echo.. I even tried removing the return command period.. Any other ideas?
