Regex: How to strip email before "@" symbol?

I have the following String

First Last <first.last@email.com>

I would like to extract

"first.last" 

from the email string using regex & PHP. How开发者_JS百科 to go about this?

Thanks in advance!

I know the answer was already accepted, but this will work on any valid email address in the format of: Name <identifier@domain>

// Yes this is a valid email address
$email = 'joey <"joe@work"@example.com>';

echo substr($email, strpos($email,"<")+1, strrpos($email, "@")-strpos($email,"<")-1);
// prints: "joe@work"

Most of the other posted solutions will fail on a number of valid email addresses.

$str ="First Last <first.last@email.com>";
$s = explode("@",$str);
$t = explode("<",$s[0]);
print end($t);

This is a lot easier (after checking that the email IS valid):

$email = 'my.name@domain.com';
$split = explode('@',$email);
$name = $split[0];
echo "$name"; // would echo "my.name"

To check validity, you could do this:

function isEmail($email) {
    return (preg_match('/[\w\.\-]+@[\w\.\-]+\.\[w\.]/', $email));
}
if (isEmail($email)) { ... }

As for extracting the email out of First Last <first.last@domain.com>,

function returnEmail($contact) {
    preg_match('\b[\w\.\-]+@[\w\.\-]+\.\[w\.]\b', $contact, $matches);
    return $matches[0];
}

Can't you just use a split function instead? I don't use PHP but seems like this would be far simpler if it's available.

If that's the exact format you'll get, then matching against the regex

/<([^@<>]+)@([^@<>]+)>/

will give you e.g. first.last in capture group 1 and email.com in capture group 2.

No need to use regexp; much more efficient to use some simple string functions.

$string = 'First Last <first.last@email.com>';
$name = trim(substr($string, 0, strpos($string, '<')));
