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 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.
