Use regex (preg_match_all) to extract e-mail from a page

When parsing a site to harvest e-mail , we use Regex with preg_match_all() function to get all e-mail but the problem is that in some html, user type email like that : abc @ gmail.com

How we solve this issue. Use this regex pattern:

$pattern="/([\s]*)([_a-zA-Z0-9-]+(\.[_a-zA-Z0-9-]+)*([ ]+|)@([ ]+|)([a-zA-Z0-9-]+\.)+([a-zA-Z]{2,}))([\s]*)/i"; preg_match_all($pattern, $html_page, $matches);

That pattern will extract all type of email.
