You should always sanitize the user’s input. But not with
addslashes()… If you want to compose a query with the user’s input, use the proper database escaping mechanism (look intomysql_real_escape_string()and PDO prepared statements).The reason for sanitizing user input is security. Read about SQL injection and cross-site scripting, which are the two most common security problems arising from un-sanitized input.
