Write php to batch generate unique card number and password codes

What this article shares with you is a very practical code that is often used in projects and can generate unique card numbers in batches There are two methods for card number passwords. Friends in need can refer to them.

When I was free, I wanted to improve my skills in array manipulation in PHP, so I wrote the following small code, which can randomly generate arrays corresponding to card numbers and passwords, and automatically remove repetitions. There is no idea, just pure in vain.

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 " 开始 ".date("H:i:s")."
