explanation need!

[rengy]

recently i am developing an web application. i refer to some example of the php code and there is some function which i not very sure the used of it. can anyone of you help to clear my doubts?

  //add slashes to the username and md5() the password 


      $user = addslashes($_POST['username']); 


     $pass = md5($_POST['password']);

this code is found in the login.php
i would like to know know why we need to add slashes to the username when we login? and what is the use of md5() ?

[bubblenut]

[man]addslashes()[/man] is performed on the username in case there are any dodgy characters which may adversely affect the database (I'm assuming this is used with a database).

[man]md5()[/man] is a one way hahing algorithm often used to make passwords unreadable when stored.

All of this could have been found by a quick search in the manual. Use it, it's your friend.

To rengy:

If you're stumped on PHP functions, try the PHP manual. Not only is it easy to understand (in my opinion), there are often times user comments where other users share workarounds or better explain situations for using the functions than the manual's explanations.
