一个集中的图书馆用户输入验证和消毒

Traditional input validation systems used on PHP-based web sites follow a distributed approach. With this approach, each script must perform its own input validation. This method is time consuming to maintain, and can be overly resource intensive. ProcessInput is a centralized script that can be called by any script on the site to safely process user input. The script can be easily updated and maintained so that it remains current to known input exploits, while remaining lightweight for use on high-traffic sites. In addition, ProcessInput features a robust yet simple error management system so scripts utilizing the system can easily spot and handle input errors.
