php身份证号计算年龄_身份证号计算年龄的公式

/*1、判断字符串是否是逗号隔开php身份证号计算年龄的数字*/

function checkNumbericStrByComma($string = "") { $pattern = "/^(\d+,)*(\d+)$/"; $ret = preg_match($pattern, $string); return $ret;}

/*2、手机号打码中间四位用*表示*/

function codeMobile($mobile = "") { return preg_replace('/(^.*)\d{4}(\d{4})$/', '\\1****\\2', $mobile);}

/*3、身份证号打码中间9-14位用*表示*/

function codeIdcard($idcard = "") { return strlen($idcard) == 15 ? substr_replace($idcard, "******", 8, 6) : (strlen($idcard) == 18 ? substr_replace($idcard, "******", 8, 6) : "");}
