php实现用于验证所有类型的信用卡类

本文实例讲述了php实现用于验证所有类型信用卡类。分享给大家供大家参考。具体如下:

这个php类比较完整,可以用于验证各种不同的信用卡,针对信用卡的卡号的通用规则进行了验证,同时对不同类型的信用卡进行了针对性的识别。
代码接受一个信用卡号码和有效日期,如果两者都有效,则返回TRUE,否则返回FALSE。

本插件接受以下参数:
$number 表示信用卡号码的一个字符串
$expiry 信用卡有效日期,采用07/12或0712这样的格式

  <?php  // Plug-in 32: Validate Credit Card  // This is an executable example with additional code supplied  // To obtain just the plug-ins please click on the Download link  $card  = "4567 1234 5678 9101";  $exp  = "06/11";  echo "Validating: $card : $exp<br>";  $result = PIPHP_ValidateCC($card, $exp);  if ($result != FALSE) echo "Card Validated";  else echo "Card did not validate";  function PIPHP_ValidateCC($number, $expiry)  {    // Plug-in 32: Validate Credit Card    //    // This plug-in accepts a credit card number and    // an expiry date and returns TRUE or FALSE,    // depending on whether the details pass date    // and checksum validation.

希望本文所述对大家的php程序设计有所帮助。
