$name = trim(fgets(STDIN));

使用php版本5.5.19 XAMPP

Answer 1

假设您从命令行界面（CLI）运行：

在文件顶部定义STDIN常量：

define('STDIN', fopen('php://stdin', 'r'));

或者只需将STDIN常量替换为：

$name = trim(fgets(fopen('php://stdin', 'r')));

Answer 2

<?php

echo "Hello there. So I hear you're learning to be a PHP programmer!\n";

echo "Why don't you type in your name for me:\n";

$stdin = fopen('php://stdin', 'r');

$name=trim(fgets($stdin));

echo "\nThanks, " . $name . ", it's really nice to meet you.\n\n";

fclose($file);
