PHP中PathInfo参数的使用

　　PHP中的全局变量$_SERVER['PATH_INFO']是一个很有用的参数，众多的CMS系统在美化自己的URL的时候，都用到了这个参数。

　　对于下面这个网址：

　　http://www.test.com/index.php/foo/bar.html?c=index&m=search

　　我们可以得到 $_SERVER['PATH_INFO'] = ‘/foo/bar.html’,而此时 $_SERVER['QUERY_STRING'] = 'c=index&m=search';

　　通常，我们最初开始PHP程序编写的时候，都会使用诸如： http://www.test.com/index.php?c=search&m=main 这样的URL，这种URL不仅看起来非常奇怪，而且对于搜索引擎也是非常不友好的。很多搜索引擎收录的时候，都会忽略Query String之后的内容，google虽然不会忽略Query String，但是对于其他不含Query String的页面，会给于比较高的PR值。

　　下面是一段解析PATH_INFO的非常简单的代码：

以下为引用的内容：

if( !isset( $_SERVER['PATH_INFO'] ) ){
$pathinfo = 'default';
}else{
$pathinfo = explode('/', $_SERVER['PATH_INFO']);
}

if( is_array($pathinfo) AND !empty($pathinfo) ){
$page = $pathinfo[1];
}else{
$page = 'a.php';
}

require "$page.php";
