PHP: Functions For Giving Birth

These are two functions I found in my archives that I had written several years ago and felt like posting.  I’m sure there are others out on the Internet, maybe even better ones.  Who cares.  Here goes…

function ZodiacSign($date){
    list($year,$month,$day)=explode("-",$date);
    if (($month==1 && $day>20)||($month==2 && $day<20)) {
        return "Aquarius";
    } else if (($month==2 && $day>18 )||($month==3 && $day<21)) {
        return "Pisces";
    } else if (($month==3 && $day>20)||($month==4 && $day<21)) {
        return "Aries";
    } else if (($month==4 && $day>20)||($month==5 && $day<22)) {
        return "Taurus";
    } else if (($month==5 && $day>21)||($month==6 && $day<22)) {
        return "Gemini";
    } else if (($month==6 && $day>21)||($month==7 && $day<24)) {
        return "Cancer";
    } else if (($month==7 && $day>23)||($month==8 && $day<24)) {
        return "Leo";
    } else if (($month==8 && $day>23)||($month==9 && $day<24)) {
        return "Virgo";
    } else if (($month==9 && $day>23)||($month==10 && $day<24)) {
        return "Libra";
    } else if (($month==10 && $day>23)||($month==11 && $day<23)) {
        return "Scorpio";
    } else if (($month==11 && $day>22)||($month==12 && $day<23)) {
        return "Sagittarius";
    } else if (($month==12 && $day>22)||($month==1 && $day<21)) {
        return "Capricorn";
    }
}

function BirthStone($iMonth) {
    switch($iMonth) {
    case 1:
        return "Garnet";
    case 2:
        return "Amethyst";
    case 3:
        return "Aquamarine";
    case 4:
        return "Diamond";
    case 5:
        return "Emerald";
    case 6:
        return "Pearl";
    case 7:
        return "Ruby";
    case 8:
        return "Peridot";
    case 9:
        return "Sapphire";
    case 10:
        return "Opal";
    case 11:
        return "Topaz";
    case 12:
        return "Turquoise";
    }
}

// examples:
$my_birth_stone = BirthStone(3);

$my_birth_sign = ZodiacSign('1955-03-31');
