用php生成excel文件
<?
header("Content-type:application/vnd.ms-excel");
header("Content-Disposition:filename=test.xls");
echo "test1\t";
echo "test2\t\n";
echo "test1\t";
echo "test2\t\n";
echo "test1\t";
echo "test2\t\n";
echo "test1\t";
echo "test2\t\n";
echo "test1\t";
echo "test2\t\n";
echo "test1\t";
echo "test2\t\n";
?>
在php环境运行上面的代码，大家就可以看到浏览器询问用户是否下载excel文档，点击保存，硬盘上就多了一个excel的文件，使用excel打开就会看到最终的结果，怎么样不错吧。
其实在做真正的应用的时候，大家可以将数据从数据库中取出，然后按照每一列数据结束后加\t,每一行数据结束后加\n的方法echo出来，在php的开头用header("Content-type:application/vnd.ms-excel");表示输出的是excel文件，用header("Content-Disposition:filename=test.xls");表示输出的文件名为text.xls。这样就ok了。
我们更可以修改header让他输出更多格式的文件，这样php在处理各种类型文件方面就更加方便了．

[2]PHP中GET变量的使用
来源: 互联网 发布时间: 2013-11-30
自PHP4.1.0以后将HTTP_GET_VARS使用GET变量来保存，GET的变量主要来自以下的方法
对服务器以获取资料信息为请求方法的例如，URL，使用FORM的METHOD为GET方式。这样所有的请求变量将通过
URL传递给服务器，服务器根据配置调用相关的解释器来处理这些GET出来的变量。
本文针对URL 的GET方式传值进行讨论
我们都知道URL传值为URL？变量名=变量值
这个方式进行递交请求例如
http://www.bbs.bbc.com?page=1
这样的方法为我们现在所通用
如果变量多了可以使用'&'符号连接变量
例如： http://www.bbs.bbc.com?page=1&title=Welcome%20Sports98
以上方法为浏览器直接将变量转变到相对应的数组中，我们并不需要去过多的了解。下面为我所要讨论的话题
例如：
http://www.bbs.bbc.com?page=1,Welcome%20Sports98,Sports98,300
这个例子说明的是，我们使用','这个符号为变量分隔符号，这里我们可以用两种方法来实现，
一、修改PHP.INI
——
; List of separator(s) used by PHP to parse input URLs into variables.
; Default is "&".
; NOTE: Every character in this directive is considered as separator!
arg_separator.input = ";，"
————
二、自己编写解释语法
list($key,$value)=$_GET; //将GET变量分解出来
$tmp=explode(",",$value); //将数据分出
这个用法的优点在于，别人无法知道您传递的值是被谁使用，您自己需要明白各个值的使用
++++++++++++++++++++++++++++++++++++++
最后针对
http://www.bbs.bbc.com/index.php?123,123433,234524,34563456,5463,78685,abc,Welcome%20Sports98
这一类的GET方法的传值，其实方法与方法二相同，需要的是将KEY转换成VALUE进行分解，我觉得这个方法比上一个方法要好
而且更加方便.
$value=key($_GET);
$tmp=explode(",",$value);
你应该都已经获得到这些数据了。
以上方法为本人浏览其他站点所看到现象所想到的方法，不知是否正确。对于PHP的默认安装用户都喜欢使用默认的GET传值方式
如果是公司有特定要求的可以考虑使用后面的方法~
学有所限，如有不对还请指正.
