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：

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 /** * 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 ( empty ( $birth_year ) || empty ( $birth_month ) || empty ( $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' );
