本文实例讲述了PHP常用函数之根据生日计算年龄功能,分享给大家供大家参考,具体如下:
- /**
- * 根据出生年月日计算出年龄
- * @param $birth_year
- * @param $birth_month
- * @param $birth_day
- * @return int
- */
- function getAgeByBirth($birth_year,$birth_month,$birth_day){
- if(emptyempty($birth_year) || emptyempty($birth_month) || emptyempty($birth_day)){
- return 0;
- }
- $current_year = date('Y',time());
- $current_month = date('m',time());
- $current_day = date('d',time());
- if($birth_year >= $current_year){
- return 0;
- }
- $age = $current_year - $birth_year - 1;
- if($current_month>$birth_month){
- return $age+1;
- }else if($current_month == $birth_month && $current_day>=$birth_day){
- return $age+1;
- }else{
- return $age;
- }
- }
- //测试:
- echo getAgeByBirth('1988','8','8');
运行结果:31
