闲的蛋疼的时候,顺便加强下自己对PHP中数组操纵的一些技巧,就写了下面的一段小代码,可以随机生成卡号密码对应的数组,并且自动去重复,思路没有,纯粹瞎掰。

<&#63;php header('Content-Type:text/html; charset=utf-8');
 function MakeCard()
 {
  set_time_limit(0);

  //处理缓冲区
  ob_end_clean();
  ob_implicit_flush(true);
  echo str_pad(" ", 256);

  if(intval($_POST['num']>0)) $num=intval($_POST['num']); //数量
  if(intval($_POST['point']>0)) $point=intval($_POST['point']); //点数
  if(intval($_POST['batch']>0)) $batch=intval($_POST['batch']); //批号
  if(($_POST['ym']!="")) $ym=$_POST['ym']; //发行年月
  else $ym=date('ym');

  if($num==0) return;

  $num=$num*100; //卡的张数,即记录数

  echo "<p>开始 ".date("H:i:s")." ";

  for($i=1;$i<=$num;$i++)
  {
   $sn=sprintf("%02s%s%06s",$batch,$ym,$i);
   $seek=mt_rand(0,9999).mt_rand(0,9999).mt_rand(0,9999); //12位
   $start=mt_rand(0,20);
   $str=strtoupper(substr(md5($seek),$start,12));
   $str=str_replace("O",chr(mt_rand(65,78)),$str);
   $str=str_replace("0",chr(mt_rand(65,78)),$str);
   $row=array('sn'=>$sn,'password'=>$str,'created'=>time(),'point'=>$point);
   //查重
  //在这里加插入数据的代码.
  print_r($row);
  }
  echo " 结束 ".date("H:i:s")."";
  printf("<br>成功生成:%s万个 %s点 的密码</p>",$num/1e4,$point);
  return $num;
 } //函数结束

$_POST['num']=1;
$_POST['point']=10;
$_POST['batch']=10;
$_POST['ym']='1405';
echo MakeCard(); &#63;>

Copy after login

方法二:

<&#63;php
$numLen=16;
$pwdLen=10;
$c=100;//生成100组卡号密码
$sNumArr=range(0,9);
$sPwdArr=array_merge($sNumArr,range('A','Z'));

$cards=array();
for($x=0;$x< $c;$x++){
 $tempNumStr=array();
 for($i=0;$i< $numLen;$i++){
  $tempNumStr[]=array_rand($sNumArr);
 }
 $tempPwdStr=array();
 for($i=0;$i< $pwdLen;$i++){
  $tempPwdStr[]=$sPwdArr[array_rand($sPwdArr)];  
 }
 $cards[$x]['no']=implode('',$tempNumStr);
 $cards[$x]['pwd']=implode('',$tempPwdStr);
}
array_unique($cards);
print_r($cards);
&#63;>
Copy after login
