下载安装好就可以用,这样的集成开发环境很多,如果你已经按照其他书安装了PHP+Mysql开发环境,调试过就不用改了。我是租的空间,本地调试就没关系啦,效果一样的。

我用的代码编写软件是dreamweaver。说实话,我只使用其代码高亮和CSS功能,全部代码都是手工编写的。你用记事本或者Zend Studio等都可以(但一旦遇到问题别怪我,因为你也可以在LUNIX里面看我的教程和编写程序,甚至坐在太空船上学习,前提是不要违背我写这本书的目的。)

ftp上传工具可以用:FlashFXP等随便一个啦。 这些东西,脚本之家网站上面都有。

PHP文件我用UTF-8编码,好处是国际化,函数之间代码耦合得好,比GB2312有优势。你要用GB2312的话也行,但本书个别两三个函数你要变通一下,涉及文件、数据库、URL等的。

PHP的head有这么一行:

可以通过dreamweaver菜单:修改--页面属性,把页面编码改成utf-8(默认就是这个)。
Hello world 程序本书就不提供了,就用这个例子代替吧:
Hello world其实用到的主要是php的输出内容函数。
echo "Hello world";
?>
实例1:输出1到100的值

复制代码 代码如下:

// 以下输出1到100的值
for($i = 0;$i {
echo $i . ” \n”;
/**
* 输出到屏幕用echo关键字,.连接符相当于C语言的+。
* 双引号、转义和其他语言一样,用单引号代替双引号则达不到换行效果,大家可以试试。
*/
}
?>

把以上代码保存为*.php文件然后放到PHP服务器目录用浏览器打开路径(如:http://localhost/index.php)即可。
当然,要发布网站到网络你还需要申请个域名和空间,这就不讲了。
