    - by Matt
    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

    - by Doori Bar
    I have a mysql table of 3 integer fields. None of the fields have a unique value - but the three of them combined are unique. When I query this table, I only search by the first field. Which approach is recommended for indexing such table? Having a multiple-field primary key on the 3 fields, or setting an index on the first field, which is not unique? Thanks, Doori Bar
