第二个实例:用php从身份证中提取生日,包括15位和18位身份证:
function getIDCardInfo($IDCard,$format=1){ $result['error']=0;//0:未知错误,1:身份证格式错误,2:无错误 $result['flag']='';//0标示成年,1标示未成年 $result['tdate']='';//生日,格式如:2012-11-15 if(!preg_match("/^(\d{15}$|^\d{18}$|^\d{17}(\d|X|x))$/",$IDCard)){ $result['error']=1; return $result; }else{ if(strlen($IDCard)==18) { $tyear=intval(substr($IDCard,6,4)); $tmonth=intval(substr($IDCard,10,2)); $tday=intval(substr($IDCard,12,2)); } elseif(strlen($IDCard)==15) { $tyear=intval("19".substr($IDCard,6,2)); $tmonth=intval(substr($IDCard,8,2)); $tday=intval(substr($IDCard,10,2)); } if($tyear>date("Y")||$tyear<(date("Y")-100)) { $flag=0; } elseif($tmonth<0||$tmonth>12) { $flag=0; } elseif($tday<0||$tday>31) { $flag=0; }else { if($format) { $tdate=$tyear."-".$tmonth."-".$tday; } else { $tdate=$tmonth."-".$tday; } if((time()-mktime(0,0,0,$tmonth,$tday,$tyear))>18*365*24*60*60) { $flag=0; } else { $flag=1; } } } $result['error']=2;//0:未知错误,1:身份证格式错误,2:无错误 $result['isAdult']=$flag;//0标示成年,1标示未成年 $result['birthday']=$tdate;//生日日期 return $result; }
最后一个实例:php 提取身份证号码中的生日日期以及确定是否成年的一个函数。可以同时确定15位和18位的身份证,经本人亲测,非常好用,分享函数代码如下:
