需求:
1、执行脚本后,想去的同学输入英文名字全拼,产生随机数01-99之间的数字,
数字越大就去参加项目实践,前面已经抓到的数字,下次不能在出现相同数字。
2、第一个输入名字后,屏幕输出信息,并将名字和数字记录到文件里,程序不能退出
继续等待别的学生输入。

实现代码(请在命令行执行,而非WEB环境):

<&#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);


/**
* 获取命令行输入值
* @param string $length
* @return string
*/
function read($length='255'){
 if (!isset($GLOBALS['StdinPointer'])){
  $GLOBALS['StdinPointer']=fopen("php://stdin","r");
 }
 $line=fgets($GLOBALS['StdinPointer'],$length);
 return trim($line);
}
Copy after login
