FIGURE 24.7
The change_passwd_form.php script supplies a form where users can change their passwords.
This form is generated by the script change_passwd_form.php. This is a simple script that just
uses the functions from the output library, so we have not included the source for it here.
When this form is submitted, it triggers the change_passwd.php script, which is shown in
Listing 24.15.
