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:
