Description:
------------
There are 2 examples given in the documentation of crypt(), which cant work the way their shown.

Example 2 will, as read in the documentation, give a different hash values each time its called. But it looks like its supposed to give the same hash for same passwords so a user given password can be compared with the one saved in a databank (or the on in htpasswd).

<?php
// Set the password
$password = 'mypassword';

// Get the hash, letting the salt be automatically generated
$hash = crypt($password);
?>

Reproduce code:
---------------
On the other hand example 1 is not clear. This wont work either, unless $user_input is given and it won't really state what it should do. From the code i would state it should be used to compare passwords, but like i said its not clear.

<?php
$password = crypt('mypassword'); // let the salt be automatically generated

/* You should pass the entire results of crypt() as the salt for comparing a
   password, to avoid problems when different hashing algorithms are used. (As
   it says above, standard DES-based password hashing uses a 2-character salt,
   but MD5-based hashing uses 12.) */
if (crypt($user_input, $password) == $password) {
   echo "Password verified!";
}
else echo "Wrong Password";
?> 

Expected result:
----------------
Password verified

Actual result:
--------------
Wrong Password
