[SOLVED] Check if string contains email

[andersj]

Hello,

 

I've run into a problem where I've tried everything possible on something that really isn't so hard.

 

On my form validation, I am checking if the posted string contains an email. If it does I want to throw up an error. It's coming from a textarea so there can be as much text before or after the email, it just needs to throw up that area, if one is in there. I've tried incorporating regular expressions with no avail.

 

Your help would be much appreciated.

 

Thanks.

try this

<?php
$var = "this is my email: [email protected] ";
if (preg_match('/\b[A-Z0-9._%+-]+@[A-Z0-9.-]+\.[A-Z]{2,4}\b/si', $var))
{
die("Contains an email");
}

?>

But thanks again, your a life saver!
