How do I one-way encrypt a string in PHP?

This one is easy in PHP using the crypt function.


<?php



$mydata = 'mypassword';



$code = crypt($mydata);



?>

Remember that this is a one way function, so if you use this when storing user password information, for instance, you will not be able to send them a password reminder but rather will need to identify them based on some other info (e.g. username and email combo) and then let them reset a password.
