* $type为1的时候是虚岁,2的时候是周岁
*/
function getAgeByBirth($date,$type = 1){
 $nowYear = date("Y",time());
 $nowMonth = date("m",time());
 $nowDay = date("d",time());
 $birthYear = date("Y",$date);
 $birthMonth = date("m",$date);
 $birthDay = date("d",$date);
 if($type == 1){
 $age = $nowYear - ($birthYear - 1);
 }else{$type == 2}{
 if($nowMonth<$birthMonth){
 $age = $nowYear - $birthYear - 1;
 }elseif($nowMonth==$birthMonth){
 if($nowDay<$birthDay){
 $age = $nowYear - $birthYear - 1;
 }else{
 $age = $nowYear - $birthYear;
 }
