PHP实现的英文名字全拼随机排号脚本
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):
<?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); }
