Released 10 months ago , Last update 11 months ago

Simple, lightweight and useful tool for primary general data checks. Can be used to validate all sorts of data for your PHP website.

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, so it can be easily used to check values got by HTTP request, obtained from database, parsed XML or CSV file or any other source as soon as data are in correct format (array('key'=>'value')). Error handling is made easy and flexible. If validation process fails, you can either obtain a generated error-message or use error-details for logging and user informing in you own style.
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.
