PHP Programming

createAccount.php should read in the list of current users from the file pass.txt. If the user name already exists, inform the user that they can not use the name that they chose and present them with a link back to createAccount.html. If the user name did not already exist, add this account to the pass.txt file.

pass.txt should have the format username:SHA-1(password)

Do not save plain text passwords, you must store the Hash of the password.

After the new account has been created, present a link to a file accessData.html
