复制代码 代码如下:

public function loop(){
  $loop = 0;
  $charnum = 65;

  for(; $loop < 150; $loop++){
   $quotient = intval($loop / 26);
   $remainder = $loop % 26;

   $f = $quotient>0? chr($charnum+$quotient-1) : \'\';
   $s = $remainder>=0? chr($charnum+$remainder) : \'\';

   echo $loop .\' | \'. $quotient .\' | \'. $remainder .\' | \'. $f . $s .\"<br>\";

   
  }
 }
