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,
分享函数代码如下:
<?php //用php从身份证中提取生日,包括15位和18位身份证 function getIDCardInfo($IDCard){ $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 $result['tdate']='';//生日,格式如:2012-11-15 if(!eregi("^[1-9]([0-9a-zA-Z]{17}|[0-9a-zA-Z]{14})$",$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){ $tyear=intval("19".substr($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{ $tdate=$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: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 reason for using Dependency Injection (DI) is that it promotes loose coupling, testability, and maintainability of the code. 1) Use constructor to inject dependencies, 2) Avoid using service locators, 3) Use dependency injection containers to manage dependencies, 4) Improve testability through injecting dependencies, 5) Avoid over-injection dependencies, 6) Consider the impact of DI on performance.

PHP performance optimization can be achieved through the following steps: 1) use require_once or include_once on the top of the script to reduce the number of file loads; 2) use preprocessing statements and batch processing to reduce the number of database queries; 3) configure OPcache for opcode cache; 4) enable and configure PHP-FPM optimization process management; 5) use CDN to distribute static resources; 6) use Xdebug or Blackfire for code performance analysis; 7) select efficient data structures such as arrays; 8) write modular code for optimization execution.
