1、批量生成注册码的示例代码如下：
<?php$Codes = GenCode(100);echo '<pre>';print_r($Codes);echo '</pre>'; function GenCode($GenCount){ $CodeArr = array(); $KeyStr = '1234567890ABCDEFGHIJKLMNOPQRSTUVWXYZ'; for ($d = 1; $d <= $GenCount; $d++) { $CodeStr = ''; for ($i = 1; $i < 5; $i++) { $Keys = str_shuffle($KeyStr); $CodeStr = $CodeStr . '-' . substr($Keys,1,4); } $CodeArr[] = substr($CodeStr,1); } array_unique($Codes); return $CodeArr;}代码运行截图：
2、将上面的数据保存到 txt 文件，代码示例：
<?php$Codes = GenCode(100);SaveToTxt('./test.txt',$Codes);function SaveToTxt($FileName, $CodeArray){ $fp = fopen($FileName, "w+") or die("打开 $FileName 失败。"); fwrite($fp, implode("\r\n", $CodeArray)) or die("写入 $FileName 数据失败。"); fclose($fp);}2017-04-15
