What is Injection?
When a user is inserting any value into the text box, we
store that in a variable and place it in a query. If the
user also types any query within the text box our mysql will
run the query.
ex :
INSERT INTO students (name) VALUES ('Dinesh'); DROP TABLE
Students;
Here the user types his name as Dinesh also he write the
next query to drop the table. so this table is dropped if it
is present.
TO avoid it we use addslashes() else
mysql_real_escape_string() methods to escape from the users
query.

we store and display scores of users in different games. In MySQL, records are stored as tuples (user-id, game-id, score). Now we need to support ranks of users, i.e., each user should be informed of his current rank in the community. The challenge is to come up with the best way to store the data in MySQL so that the requirements are efficiently met.
