Question

I am attempting to create a system to validate a user’s username and password.
I am currently have issues with checking the user name…
If someone’s username is say, Burrito, when I pass the query to see if it is in the database, it will not check if the case of the letters is correct.
Example:
Username is Michael
They can enter michael or MiChAeL and it will still think it is the same username.

here is what I am using to check the username:

$isValid = mysql_query("SELECT username FROM " . getSQL_Info(3) . " WHERE username = '" . $user . "'");

Thank you for your time and help.
Also, if you see any problems with my code, if something could be better or what not, please tell me 🙂

Answer 1

• you are using deprecated mysql functions
• be aware of security

• the solution of your problem is

  SELECT * FROM foo WHERE (BINARY username=”someNaMe”)
