RegEx for an email address

Need email from the middle of a string

[trillianjedi]

I need some help from the RegEx pro's ;)

I have a string which contains all manner of junk, but an email address in the middle, something like:-

$txt='100 10 "u" "EM" "!^.*$!email:[e-mail]!"';

If it looks familiar it's a DNS NAPTR record. I need to extract the email part.

The email address will always start "!email:"

and will always end with a "!"

Is there a simple RegEx/preg I could use to extract that email addy (in this example case I'd be after "[e-mail]") to a new string?

[eeek]

Just take the start and end strings (escaping any characters that need it) and put a .* between them.

Well, I can tell you how to do it without regex. ;)

$string = '$txt=\'100 10 "u" "EM" "!^.*$!email:[e-mail]!"';

echo str_replace('!"','',substr($string,strpos($string,'email:')+6,strlen($string)));
