Test for email address in string

[carole2]

I would like a reg expression that can check for the existence of an email address in a string. This is to prevent users from entering an email address into a particular field.

Thanks that was helpful but i would like a reg expression that would allow all text except for an email address, if that is possible.

You do something like this:
[code]<?php

$text = "Hey my email adddy is abc123@abc.def isnt it nice";

if(preg_match("/([A-Z0-9._%-]+@[A-Z0-9.-]+\.[A-Z]{2,4})/i", $text))
{
    echo "Email adddy detected, We do not accept email addresses within strings!";
}
else
{
    echo "No email addy dectected";
}

?>[/code]

Thanks..
Yeah thats a possibility i thought of  that already. .. I am using a form class that validates on the server side and the client side. On the client side javascript is created from the reg expression. So i was looking for just a reg expression that would not accept any text that contained an email address. Its not that important as i could validate it on the server side only with the above code. 

Thanks for your input...
