There are a few solutions that might meet your needs. One solution in One solution that might meet your needs is php_pam (ftp://ftp.netexpress.net/pub/pam/php_pam.newest.tgz). This is a PHP extension that implements the PAM API. However, one notable deficiency in this extension is that it only works for password changing if the webserver user (nobody, or www-data, on most Linux systems) has *direct* access to change the password. If you are using standard Unix passwords in /etc/passwd or /etc/shadow, it is not a particularly good idea to give the web user this access. I will at some point be rewriting php_pam to be more flexible, but haven't had much time to point in that direction. In the meantime, it works for some people and not for others.
