PHP Extract the birthday date from the ID number and the function to verify whether it is a minor

PHP extracts the birthday date from the ID number and determines whether a function is adult.

Can be determined at the same time 15-bit and 18-bit ID card, by my pro-test, very useful, share the function code as follows:

  Use PHP to extract birthdays from your ID, including 15-and 18-bit IDs
function Getidcardinfo ($IDCard) {
$result [' Error ']=0;//0: Unknown error, 1: ID card format error, 2: Error-free
$result [' flag ']= ';//0 marked adulthood, 1 marked minors
$result [' tdate ']= ';//Birthday, Format: 2012-11-15
if (!eregi ("^[1-9") ([0-9a-za-z]{17}|[ 0-9A-ZA-Z]{14}) ($ ", $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));
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{
$tdate = $tyear. " -". $tmonth." -". $tday." 00:00:00 ";
if (Time ()-mktime (0,0,0, $tmonth, $tday, $tyear)) >18*365*24*60*60) {
$flag = 0;
}else{
$flag = 1;
}
}
}elseif (strlen ($IDCard) ==15) {
$tyear =intval (substr ($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{
$tdate = $tyear. " -". $tmonth." -". $tday." 00:00:00 ";
if (Time ()-mktime (0,0,0, $tmonth, $tday, $tyear)) >18*365*24*60*60) {
$flag = 0;
}else{
$flag = 1;
}
}
}
}
$result [' Error ']=2;//0: Unknown error, 1: ID card format error, 2: Error-free
$result [' Isadult ']= $flag;//0 marked adult, 1 marked minors
$result [' Birthday ']= $tdate;//Birthday Date
return $result;
}

Use the following:

Getidcardinfo (' ID card number ');
