Get email address from mailbox string

Question

I need to extract the email address out of this mailbox string. I thought of str_replace but the display name and the email address is not static so I don't know how to do this using regular expressions.

Example: " My name <email@example.com> " should result in " email@example.com ".

Any ideas?

Thanks Matthy

Answer 1

您可以使用imap_rfc822_parse_adrlist来解析该地址：

$addresses = imap_rfc822_parse_adrlist('My name <email@gmail.com>');

Answer 2

at face value, the following will work:

preg_match('~<([^>]+)>~',$string,$match);

but i have a sneaking suspicion you need something better than that. There are a ton of "official" email regex patterns out there, and you should be a bit more specific about the context and rules of the match.

Answer 3

If you know that the string is surrounded by < and > you can simply split out according to that.

This assumes that you will always have only one pair of < and > surrounding the string, and it will not ensure that the result is an email pattern.

Otherwise you can always read up on email regex patterns .

Answer 4

or Look up regular expressions (preg_match).

something like: [^<] <([^>] )>;

Answer 5

I'm coming from a time and from projects where Regex was to expensive for easy string extraction.

$s = 'My name <email@gmail.com>';
$s = substr(($s = substr($s, (strpos($s, '<')+1))), 0, strrpos($s, '>'));

Results in

email@gmail.com
