PHP实现的英文名字全拼随机排号脚本

// 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 "rnEnter 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."rn");

$user[$n] = $content;

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

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

fwrite($handle,"rn");
fwrite($handle,'----------------华丽的分隔线-----------------');
fwrite($handle,"rn");

ksort($user);

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

// 关闭文件
fclose($handle);
