本人零基础想学习写一个最简单的php程序 hello world但不知道怎从网上下载与安装并写出来？

先学PHP基础，再去百度查自己需要的功能的原理，然后去实验，实验成功后在网站上使用它。
走完这四步，你才算学会了这门技术的一个功能。
学不会PHP人绝大部分一直在重复第一步！

w3school上的教程非常的基础，很容易懂，建议先看完它。然后可以看看php100的视频教程，这个讲得很细很易懂，而且讲知识点非常的多，我也是看这个学会的。
还是那句话，看教程只是在背乘法口诀，只会乘法口诀的学生从来都不会做应用题，只有使用它，那才是真正的学习！

本人零基础想学习写一个最简单的php程序 hello world但不知道怎从网上下载与安装并写出来

最简单的程序就这样：
echo 'Hello, world!';
?>

下载PHP可以在www.php.net下载，选择windows下的二进制代码，可以下载安装包和ZIP包，我喜欢ZIP包，随便解压缩到一个文件夹就可以了，例如c:\php\下。双击上面保存的（我用记事本编辑）PHP文件，选择和你刚才解开的c:\php\php.exe关联就可以了。
