php中根据生日判断星座、生肖程序代码
星座判断很简单我们要统计出每个星期所有日期时间段了,然后获取日期进行查询即可了,下面我给大家举两个实例,有需要的同学可参考.
星座:我是根据这个时间表写的,该时间表未必准确.
'水瓶座'=>'(1/22-2/21)', '双鱼座'=>'(2/22-3/21)',
'白羊座'=>'(3/22-4/21)', '金牛座'=>'(4/22-5/21)',
'双子座'=>'(5/22-6/21)', '巨蟹座'=>'(6/22-7/21)',
'狮子座'=>'(7/22-8/21)', '处女座'=>'(8/22-9/21)',
'天秤座'=>'(9/22-10/21)', '天蝎座'=>'(10/22-11/21)',
'射手座'=>'(11/22-12/21)', '摩羯座'=>'(12/22-1/21)'
根据日期判断星座函数
实例代码如下:
- function yige_constellation($month, $day) {
 - // 检查参数有效性
 - if ($month < 1 || $month > 12 || $day < 1 || $day > 31) return false;
 - // 星座名称以及开始日期
 - $constellations = array(
 - array( "20" => "宝瓶座"),
 - array( "19" => "双鱼座"),
 - array( "21" => "白羊座"),
 - array( "20" => "金牛座"),
 - array( "21" => "双子座"),
 - array( "22" => "巨蟹座"),
 - array( "23" => "狮子座"),
 - array( "23" => "处女座"),
 - array( "23" => "天秤座"),
 - array( "24" => "天蝎座"),
 - array( "22" => "射手座"),
 - array( "22" => "摩羯座")
 - );
 - list($constellation_start, $constellation_name) = each($constellations[(int)$month-1]);
 - if ($day < $constellation_start) list($constellation_start, $constellation_name) = each($constellations[($month -2 < 0) ? $month = 11: $month -= 2]);
 - return $constellation_name;
 - }
 
下面这个更全面可直接根据生日检查年龄,生肖,星座
实例代码如下:
- <?php
 - /**
 - * 根据生日中的月份和日期来计算所属星座
 - *
 - * @param int $birth_month
 - * @param int $birth_date
 - * @return string
 - */
 - function get_constellation($birth_month,$birth_date)
 - {
 - //判断的时候,为避免出现1和true的疑惑,或是判断语句始终为真的问题,这里统一处理成字符串形式
 - $birth_month = strval($birth_month);
 - $constellation_name = array(
 - '水瓶座','双鱼座','白羊座','金牛座','双子座','巨蟹座',
 - '狮子座','处女座','天秤座','天蝎座)','射手座','摩羯座'
 - );
 - if ($birth_date <= 22)
 - {
 - if ('1' !== $birth_month)
 - {
 - $constellation = $constellation_name[$birth_month-2];
 - }
 - else
 - {
 - $constellation = $constellation_name[11];
 - }
 - }
 - else
 - {
 - $constellation = $constellation_name[$birth_month-1];
 - }
 - return $constellation;
 - }
 - /**
 - * 根据生日中的年份来计算所属生肖
 - *
 - * @param int $birth_year
 - * @return string
 - */
 - function get_animal($birth_year)
 - {
 - //1900年是子鼠年
 - $animal = array(
 - '子鼠','丑牛','寅虎','卯兔','辰龙','巳蛇',
 - '午马','未羊','申猴','酉鸡','戌狗','亥猪'
 - );
 - $my_animal = ($birth_year-1900)%12;
 - return $animal[$my_animal];
 - }
 - /**
 - * 根据生日来计算年龄
 - *
 - * 用Unix时间戳计算是最准确的,但不太好处理1970年之前出生的情况
 - * 而且还要考虑闰年的问题,所以就暂时放弃这种方式的开发,保留思想
 - *
 - * @param int $birth_year
 - * @param int $birth_month
 - * @param int $birth_date
 - * @return int
 - */
 - function get_age($birth_year,$birth_month,$birth_date)
 - {
 - $now_age = 1; //实际年龄,以出生时为1岁计
 - $full_age = 0; //周岁,该变量放着,根据具体情况可以随时修改
 - $now_year = date('Y',time());
 - $now_date_num = date('z',time()); //该年份中的第几天
 - $birth_date_num = date('z',mktime(0,0,0,$birth_month,$birth_date,$birth_year));
 - $difference = $now_date_num - $birth_date_num;
 - if ($difference > 0)
 - {
 - $full_age = $now_year - $birth_year;
 - }
 - else
 - {
 - $full_age = $now_year - $birth_year - 1;
 - }
 - $now_age = $full_age + 1;
 - return $now_age;
 - }
 - ?>
