本文实例讲述了php实现用于验证所有类型的信用卡类。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. The arguments required // are: // $number: Credit Card Number // $expiry: Expiry date in the form: // 07/12 or 0712 (for July, 2012) $number = preg_replace( /[^d]/ , , $number); $expiry = preg_replace( /[^d]/ , , $expiry); $left = substr($number, 0, 4); $cclen = strlen($number); $chksum = 0; // Diners Club if (($left = 3000) ($left = 3059) || ($left = 3600) ($left = 3699) || ($left = 3800) ($left = 3889)) if ($cclen != 14) return FALSE; // JCB if (($left = 3088) ($left = 3094) || ($left = 3096) ($left = 3102) || ($left = 3112) ($left = 3120) || ($left = 3158) ($left = 3159) || ($left = 3337) ($left = 3349) || ($left = 3528) ($left = 3589)) if ($cclen != 16) return FALSE; // American Express elseif (($left = 3400) ($left = 3499) || ($left = 3700) ($left = 3799)) if ($cclen != 15) return FALSE; // Carte Blanche elseif (($left = 3890) ($left = 3899)) if ($cclen != 14) return FALSE; // Visa elseif (($left = 4000) ($left = 4999)) if ($cclen != 13 $cclen != 16) return FALSE; // MasterCard elseif (($left = 5100) ($left = 5599)) if ($cclen != 16) return FALSE; // Australian BankCard elseif ($left == 5610) if ($cclen != 16) return FALSE; // Discover elseif ($left == 6011) if ($cclen != 16) return FALSE; // Unknown else return FALSE; for ($j = 1 - ($cclen % 2); $j $cclen; $j += 2) $chksum += substr($number, $j, 1); for ($j = $cclen % 2; $j $cclen; $j += 2) $d = substr($number, $j, 1) * 2; $chksum += $d 10 ? $d : $d - 9; if ($chksum % 10 != 0) return FALSE; if (mktime(0, 0, 0, substr($expiry, 0, 2), date( t ), substr($expiry, 2, 2)) time()) return FALSE; return TRUE;?
