使用未定义的常量STDIN-在第5行的C:\ wamp \ www \ study \ sayHello.php中假定为"STDIN" [英] Use of undefined constant STDIN - assumed 'STDIN' in C:\wamp\www\study\sayHello.php on line 5

问题描述

我想学习php& mySQL和我购买了一本书(php& mySql:缺少的手册2edition)

I want to Learn php & mySQL and I purchased a book (php&mySql: the missing manuals 2edition)

我在win8 64位计算机上安装了Wampserver2.4.

I installed Wampserver2.4 on win8 64bit machine.

服务器配置

Apache版本:2.4.4
PHP版本:5.4.12

Apache Version : 2.4.4
PHP Version : 5.4.12

在第一课中，我得到了这个错误:(

in first lesson i got this error :(

Notice: Use of undefined constant STDIN - assumed 'STDIN' in C:\wamp\www\study\sayHello.php on line 5

这是文件"sayHello.php"上的php代码

this is the php code on file "sayHello.php"

<?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";
$name = trim(fgets(STDIN));

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

?>

推荐答案

只需在文件顶部定义STDIN常量，

Just define STDIN constant at top of your file,

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