ApPHP DataValidator is a simple lightweight tool useful for primary general data checks. It handles numbers, strings, emails, URLs. A range of parameters is provided for a wide variety of different verifications. All parameters are used optionally and could be switched on and off for every specific value. The DataValidator component accepts an array or an object as data container. Data validation is typically used to make sure that incoming data has a certain quality/value. The validation process is running on a server-side. This component may be used for: - Database data validation, - Function parameters or returned values validation, - Web forms data validation, etc.
