本文主要为大家详细介绍了使用php从身份证号中获取一系列线索，比如星座、生肖、生日等，PHP从提取身份证号码中的生日并验证是否成年的函数，感兴趣的小伙伴们可以参考一下。希望对大家有所帮助。
具体内容如下
<?phpfunction get_xingzuo($cid) { // 根据身份证号，自动返回对应的星座 if (!isIdCard($cid)) return ''; $bir = substr($cid,10,4); $month = (int)substr($bir,0,2); $day = (int)substr($bir,2); $strValue = ''; if (($month == 1 && $day >= 20) || ($month == 2 && $day <= 18)) { $strValue = "水瓶座"; } else if (($month == 2 && $day >= 19) || ($month == 3 && $day <= 20)) { $strValue = "双鱼座"; } else if (($month == 3 && $day > 20) || ($month == 4 && $day <= 19)) { $strValue = "白羊座"; } else if (($month == 4 && $day >= 20) || ($month == 5 &am<strong>）本文来（源gaodai#ma#com搞@@代~&码*网2</strong><pre>搞代gaodaima码
