apache_lookup_uri — 对指定的 URI 执行部分请求并返回所有有关信息
$filename
)本函数对一个 URL 执行部分请求。取得所有有关给定资源的重要信息后就停手。
、 仅在将 PHP 安装为 Apache 模块时,支持此函数。
filename
被请求的文件名(URI)。
一个有关 URI 信息的 object 。此 object 的属性有:
Example #1 apache_lookup_uri() 例子
<?php
$info = apache_lookup_uri ( 'index.php?var=value' );
print_r ( $info );
if ( file_exists ( $info -> filename )) {
echo 'file exists!' ;
}
?>
以上例程的输出类似于:
stdClass Object ( [status] => 200 [the_request] => GET /dir/file.php HTTP/1.1 [method] => GET [mtime] => 0 [clength] => 0 [chunked] => 0 [content_type] => application/x-httpd-php [no_cache] => 0 [no_local_copy] => 1 [unparsed_uri] => /dir/index.php?var=value [uri] => /dir/index.php [filename] => /home/htdocs/dir/index.php [args] => var=value [allowed] => 0 [sent_bodyct] => 0 [bytes_sent] => 0 [request_time] => 1074282764 ) file exists!

bug: with apache 2, apache_lookup_uri("/directory") spits out a warning and fails to return anything. apache_lookup_uri("/directory/") works.
another bug: virtual("something") forces a header flush. I know it's documented, but it would be rather wonderful if it didn't do this. You never ever want to flush headers when you're using virtual() to include a dynamic file such as a PHP or Perl file, which excludes virtual() from being used on most of any website's contents :-(.

It's a very usefull function but it doesn't show all outputs. For example I only see:
[status]
[the_request]
[method]
[mtime]
[clength]
[chunked]
[content_type]
[no_cache]
[no_local_copy]
[unparsed_uri]
[uri]
[filename]
[path_info]
[allowed]
[sent_bodyct]
[bytes_sent]
[request_time]

A useful feature is that if you have content negotiation on (Options MultiViews) Apache will resolve the negotiation for you if possible. Thus www.example.com/blah will resolve to /base/blah.php or /base/blah.html or even /base/blah.en.html as appropriate.
