[开发测试]php获取年龄、属相、星座

 function birthday($mydate,$symbol='-'){

        //计算年龄
        $birth=$mydate;
        list($by,$bm,$bd)=explode($symbol,$birth);
        $cm=date('n');
        $cd=date('j');
        $age=date('Y')-$by-1;
        if ($cm>$bm || $cm==$bm && $cd>$bd) $age++;
        $array['age'] = $age;

        //计算生肖
        $animals = array(
            '鼠', '牛', '虎', '兔', '龙', '蛇',
            '马', '羊', '猴', '鸡', '狗', '猪'
        );
        $key = ($by - 1900) % 12;
        $array['animals'] = $animals[$key];

        //计算星座
        $month = $bm;
        $day = $bd;
        $signs = array(
            array('20'=>'水瓶座'), 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')
        );
        $key = (int)$month - 1;
        list($startSign, $signName) = each($signs[$key]);
        if( $day < $startSign ){
            $key = $month - 2 < 0 ? $month = 11 : $month -= 2;
            list($startSign, $signName) = each($signs[$key]);
        }
        $array['constellation'] = $signName;
    
        return $array;
    }

注意：根据某些方式，有如下方式，获取到的星座，在 1-22日获取到的星座错误

 $constellation_name = array(
            '水瓶座','双鱼座','白羊座','金牛座','双子座','巨蟹座',
            '狮子座','处女座','天秤座','天蝎座','射手座','摩羯座'）；
if ($day<= 22){
            if ('1' != $month) $constellation = $constellation_name[$bm-2]; else $constellation = $constellation_name[11];
        }else $constellation = $constellation_name[$month-1];
        $array['constellation'] = $constellation;
