mapkyca / strip_replies_regexp.php
Created August 1, 2013 15:39
Strip email replies from an email message body. Note, this regex is simplistic, since stripping replies reliably is a whole world of hurt.
// Try simple regex, strip quoted (&gt;) replies from an email
return preg_replace('/(^\w.+:\n)?(^&gt;.*(\n|$))+/mi', '', $message);
// Try simple regex, strip replies from email using >
return preg_replace('/(^\w.+:\n)?(^>.*(\n|$))+/mi', '', $message);
