PHP实现的英文名字全拼随机排号脚本

<&#63;php

// 号码库
$num = range(1, 99);

// 随机打乱
shuffle($num);

$filename = './user.txt';

// 打开记录文件
$handle = fopen($filename, 'w');

// 排序后的用户列表
$user = array();

while (true) {
 echo "\r\nEnter your name:";

 $content = read();

 // exit 退出脚本
 if ($content == 'exit') {
  break;
 }

 // 取出随机值
 $n = array_pop($num);

 // 写入文件
 fwrite($handle, $n.' '.$content."\r\n");

 $user[$n] = $content;

 // 输出到控制台
 echo "Hi $content, your number is " . $n."\r\n";
}

// 关闭控制到输入流
fclose($GLOBALS['StdinPointer']);

fwrite($handle, "\r\n");
fwrite($handle, '----------------华丽的分隔线-----------------');
fwrite($handle, "\r\n");

ksort($user);

foreach ($user as $k=>$v) {
 fwrite($handle, $k.' '.$v."\r\n");
}

// 关闭文件
fclose($handle);
