/***根据出生年月日计算出年龄*@param$birth_year*@param$birth_month*@param$birth_day*@returnint*/functiongetAgeByBirth($birth_year,$birth_month,$birth_day){if(empty($birth_year)||empty($birth_month)||empty($birth_day)){return0;}$current_year=date('Y',time());$current_month=date('m',time());$current_day=date('d',time());if($birth_year>=$current_year){return0;}$age=$current_year-$birth_year-1;if($current_month>$birth_month){return$age+1;}elseif($current_month==$birth_month&&$current_day>=$birth_day){return$age+1;}else{return$age;}}//测试：echogetAgeByBirth('1988','8','8');
运行结果：
31
