本文章来给大家总结了一些常用的php根据出生日期计算年龄 生肖 星座程序,希望给各位同学所有帮助了。
例1
 代码如下 复制代码
function getage($birthday) {
 $age = 0;
 $year = $month = $day = 0;
 if (is_array($birthday)) {
  extract($birthday);
 } else {
  if (strpos($birthday, '-') !== false) {
   list($year, $month, $day) = explode('-', $birthday);
   $day = substr($day, 0, 2); //get the first two chars in case of '2000-11-03 12:12:00'
  }
 }
 $age = date('y') - $year;
 if (date('m')  return $age;
}
例2
 代码如下 复制代码
function age($birth) {
 $age = array();
 //$now = date('ymd');
 $now = 20110228;
 //分解当前日期为年月日
 $nowyear = (int) ($now / 10000);
 $nowmonth = (int) (($now % 10000) / 100);
 $nowday = $now % 100;
//分解出生日期为年月日
 $birthyear = (int) ($birth / 10000);
 $birthmonth = (int) (($birth % 10000) / 100);
 $birthday = $birth % 100;
$year  = $nowyear - $birthyear;
 if ($birthmonth>$nowmonth){
  $year--;
 }else if($birthmonth==$nowmonth){
  if($birthday==29&&$birthmonth=2){
/*    if($nowyear>3200||($nowyear%3200==0&&$nowyear%172800==0)){
    if($birthday>$nowday){
     $year--;
    }
   }else if($nowyear==3200){
    if (($birthday>$nowday)&&$nowday!=28){
     $year--;
    }
   }else */
   if ($nowyear%400==0||(($nowyear%4==0)&&($nowyear%100!=0))){
    if($birthday>$nowday){
     $year--;
    }
   }
  }
 }
return $year;
}
