extract email adress

[kristijan]

hi,

i wanna expand this code and make email-adresses also active.
i'm not so good with RegEx. Could somebody please help me how to extract an email adress?

many thanx.
c

if (ereg("www.(.)([^.].)(.{1,3})", mysql_result($result, $i, "Text"), $match)) {

$repl = ereg_replace($match[0], "<a href=http://www.$match[1]$match[2]$match[3]>$match[0]</a>" , "<p><font face='Arial' size='1' color='#000000'>" . nl2br(htmlentities(stripslashes(mysql_result($result, $i, "Text")))) . "</font></p>");
print "$repl";
} else {
print "<p><font face='Arial' size='1' color='#000000'>" . nl2br(htmlentities(stripslashes(mysql_result($result, $i, "Text")))) . "</font>";
}

I use this perl regexp to validate emails from forms.

#^[\w\-]+(\.[\w\-])*@\w+(\.\w+)*(\.[a-z]{2,4})$#i

You could modify it like this and use preg_replace()

<?php
$body = preg_replace('#\b([\w\-]+(\.[\w\-])*@\w+(\.\w+)*(\.[a-z]{2,4}))\b#i', '<a href="mailto:\\1">\\1</a>', $body);
?>

Try that out, it should work.
