php-iban is a PHP library for parsing and validating IBAN bank account information. All parts of an IBAN can be retrieved, including country code, checksum, BBAN, financial institution or bank code, and where a fixed-length national system is in use, also branch/sort code and account number. The parser was built using regular expressions to adapt the contents of the official IBAN registry available from SWIFT then only manually modified for a few special cases. Various deficiencies in the initial adaptation have since been rectified, and the current version should be a fairly correct and reliable implementation.

If the fields are invalid, an error message is displayed inside a page element for displaying validation errors.
Data Validator is a class to validate a set of values based on a list of rules. It supports the following validation orders: sequence (fields validated sequentially), all-at-once, and both (using a dependencies model).
