* * @var string */ var $CCVSType = ''; /** * The card's expiration date. * *Presented only if the RequireExp parameter is * Y and there are no other problems with the card * number, this variable contains the expiration date in * MMYY format.
* * @var string */ var $CCVSExpiration = ''; /** * String explaining the first problem detected, if any. * @var string */ var $CCVSError = ''; /** * Ensures credit card information is keyed in correctly. * *Checks that the length is correct, the first four digits are * within accepted ranges, the number passes the Mod 10 / Luhn * checksum algorithm and that you accept the given type of card. It * also determines the card's type via the number's first four digits.
* *The procedure has the option to check the card's expiration date.
* *Error messages are internationalized through use of variables * defined by files in the ./language subdirectory. These * files are named after their ISO 639-1 two letter language code. * The language used depends on the code put in the * $Language parameter.
* *Just to be clear, this process does not check with banks or * credit card companies to see if the card number given is actually * associated with a good account. It just checks to see if the * number matches the expected format.
* *Warning: this function uses exact number ranges as part of * the validation process. These ranges are current as of * 30 July 2002. If presently undefined ranges come into use * in the future, this program will improperly deject card numbers * in such ranges, rendering an error saying "First four digits * indicate unknown card type." If this happens while entering a * card and type you KNOW are valid, please contact us so we can * update the ranges.
* *This function requires PHP to be at version 4.0 or above.

* *Several people deserve praise for the Credit Card Validation * Solution. I learned of the Mod 10 Algorithm in some Perl code, * entitled "The Validator," available on Matt's Script Archive, * http://www.scriptarchive.com/ccver.html. That code was written by * David Paris, who based it on material Melvyn Myers reposted from an * unknown author. Paris credits Aries Solis for tracking down the data * underlying the algorithm. I pruned down the algorithm to it's core * components, making things smaller, cleaner and more flexible. Plus, * I added the expiration date checking routine. My first attemts at * this were in Visual Basic, on which Allen Browne and Rico Zschau * assisted. Neil Fraser helped a bit on the Perl version. Steve * Horsley, Roedy Green and Jon Skeet provided tips on the Java Edition.
