sql-injection

Hi,

I want to develop a function in PHP that checks how dangerous a SQL statement is. When i say dangerous i mean, certain symbols, characters or strings that are used to get data from a database that the user shouldnt see.

For example:

SELECT * FROM users WHERE userId = '1'

can be injected in several ways. Although i clean the params, i also want to monitor how safe the query is to run.

Thanks in advance
