Use PHP to get a series of clues from the ID number (zodiac sign, zodiac sign, birthday, etc.) Sun Kebin ID number Taiwan ID number Hong Kong ID number

The first example of this article shares with you how PHP can automatically obtain the corresponding constellation function based on the ID card number for your reference. The specific content is as follows

= 20) || ($month == 2 && $day = 19) || ($month == 3 && $day  20) || ($month == 4 && $day = 20) || ($month == 5 && $day = 21) || ($month == 6 && $day  21) || ($month == 7 && $day  22) || ($month == 8 && $day = 23) || ($month == 9 && $day = 23) || ($month == 10 && $day  23) || ($month == 11 && $day  22) || ($month == 12 && $day  21) || ($month == 1 && $day 

The second example: Use PHP to extract the birthday from the ID card. Including 15-digit and 18-digit ID cards:

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)); 
  $tm 
  $tday=intval(substr($IDCard,12,2)); 
 }
 elseif(strlen($IDCard)==15)
 { 
  $tyear=intval("19".substr($IDCard,6,2)); 
  $tm 
  $tday=intval(substr($IDCard,10,2)); 
 }
  
 if($tyear>date("Y")||$tyear12)
  { 
  $flag=0; 
  }
  elseif($tday31)
  { 
  $flag=0; 
  }else
  { 
  if($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; 
}

The last example: php is a function to extract the birthday date from the ID card number and determine whether it is an adult. It can determine 15-digit and 18-digit ID cards at the same time. After personal testing, it is very easy to use. The shared function code is as follows:

date("Y")||$tyear){
    $flag=;
   }elseif($tday){
    $flag=;
   }else{
    $tdate=$tyear."-".$tmonth."-".$tday." ::";
    if((time()-mktime(,,,$tmonth,$tday,$tyear))>****){
     $flag=;
    }else{
     $flag=;
    }
   }
  }elseif(strlen($IDCard)==){
   $tyear=intval("".substr($IDCard,,));
   $tm
   $tday=intval(substr($IDCard,,));
   if($tyear>date("Y")||$tyear){
    $flag=;
   }elseif($tday){
    $flag=;
   }else{
    $tdate=$tyear."-".$tmonth."-".$tday." ::";
    if((time()-mktime(,,,$tmonth,$tday,$tyear))>****){
     $flag=;
    }else{
     $flag=;
    }
   }
  }
 }
 $result['error']=;//：未知错误，：身份证格式错误，：无错误
 $result['isAdult']=$flag;//标示成年，标示未成年
 $result['birthday']=$tdate;//生日日期
 return $result;
}

The usage is as follows:

getIDCardInfo('ID card number');

The above code is the php function that the editor shared with you to extract the birthday date from the ID card number and verify whether it is an adult. I hope it will be useful to everyone.

The above introduces the use of PHP to obtain a series of clues (zodiac sign, zodiac sign, birthday, etc.) from the ID number, including the content of the ID number. I hope it will be helpful to friends who are interested in PHP tutorials.
