使用php从身份证号中获取一系列线索（星座、生肖、生日等）

本文第一个实例为大家分享了PHP根据身份证号，自动获取对应的星座函数，供大家参考，具体内容如下

<?phpfunction get_xingzuo($cid) { // 根据身份证号，自动返回对应的星座  if (!isIdCard($cid)) return '';  $bir = substr($cid,10,4);  $month = (int)substr($bir,0,2);  $day = (int)substr($bir,2);  $strValue = '';  if (($month == 1 && $day >= 20) || ($month == 2 && $day <= 18)) {    $strValue = "水瓶座";  } else if (($month == 2 && $day >= 19) || ($month == 3 && $day <= 20)) {    $strValue = "双鱼座";  } else if (($month == 3 && $day > 20) || ($month == 4 && $day <= 19)) {    $strValue = "白羊座";  } else if (($month == 4 && $day >= 20) || ($month == 5 && $day <= 20)) {    $strValue = "金牛座";  } else if (($month == 5 && $day >= 21) || ($month == 6 && $day <= 21)) {    $strValue = "双子座";  } else if (($month == 6 && $day > 21) || ($month == 7 && $day <= 22)) {    $strValue = "巨蟹座";  } else if (($month == 7 && $day > 22) || ($month == 8 && $day <= 22)) {    $strValue = "狮子座";  } else if (($month == 8 && $day >= 23) || ($month == 9 && $day <= 22)) {    $strValue = "处女座";  } else if (($month == 9 && $day >= 23) || ($month == 10 && $day <= 23)) {    $strValue = "天秤座";  } else if (($month == 10 && $day > 23) || ($month == 11 && $day <= 22)) {    $strValue = "天蝎座";  } else if (($month == 11 && $day > 22) || ($month == 12 && $day <= 21)) {    $strValue = "射手座";  } else if (($month == 12 && $day > 21) || ($month == 1 && $day <= 19)) {    $strValue = "魔羯座";  }  return $strValue;   }function get_shengxiao($cid) { //根据身份证号，自动返回对应的生肖  if (!isIdCard($cid)) return '';  $start = 1901;  $end = $end = (int)substr($cid,6,4);  $x = ($start - $end) % 12;  $value = "";      if ($x == 1 || $x == -11) {$value = "鼠";}  if ($x == 0) { $value = "牛";}  if ($x == 11 || $x == -1) {$value = "虎";}  if ($x == 10 || $x == -2) {$value = "兔";}  if ($x == 9 || $x == -3) {$value = "龙";}  if ($x == 8 || $x == -4) {$value = "蛇";}  if ($x == 7 || $x == -5) {$value = "马";}  if ($x == 6 || $x == -6) {$value = "羊";}  if ($x == 5 || $x == -7) {$value = "猴";}  if ($x == 4 || $x == -8) {$value = "鸡";}  if ($x == 3 || $x == -9) {$value = "狗";}  if ($x == 2 || $x == -10) {$value = "猪";}  return $value;}function get_xingbie($cid) { //根据身份证号，自动返回性别  if (!isIdCard($cid)) return '';  $sexint = (int)substr($cid,16,1);     return $sexint % 2 === 0 ? '女' : '男';}function isIdCard($number) { // 检查是否是身份证号  // 转化为大写，如出现x  $number = strtoupper($number);  //加权因子   $wi = array(7, 9, 10, 5, 8, 4, 2, 1, 6, 3, 7, 9, 10, 5, 8, 4, 2);  //校验码串   $ai = array('1', '0', 'X', '9', '8', '7', '6', '5', '4', '3', '2');  //按顺序循环处理前17位   $sigma = 0;  for ($i = 0;$i < 17;$i++) {     //提取前17位的其中一位，并将变量类型转为实数     $b = (int) $number{$i};      //提取相应的加权因子     $w = $wi[$i];     //把从身份证号码中提取的一位数字和加权因子相乘，并累加    $sigma += $b * $w;   }  //计算序号   $snumber = $sigma % 11;    //按照序号从校验码串中提取相应的字符。   $check_number = $ai[$snumber];   if ($number{17} == $check_number) {    return true;  } else {    return false;  }}?>
