一个判断干支、属相和星座的php函数

一个判断干支、属相和星座的php函数 - 不足的是 星座应该是区分公历算的~~  有待改进

php代码

$arr = birthext ( '474768000' ); //时间戳
print_r ( $arr );
$arr = birthext ( '1985-01-17' );
print_r ( $arr );
$arr = birthext ( '19850117' );
print_r ( $arr );

php代码：

function birthext($birth)
{
    if (strstr ( $birth, '-' ) === false && strlen ( $birth ) !== 8)
        $birth = date ( "Y-m-d", $birth );
    if (strlen ( $birth ) === 8)
    {

    }
     
    if (strlen ( $birth ) < 8)
