示範 1.apache_lookup_uri() example
`<?php $info = apache_lookup_uri('index.php?var=value'); print_r($info); if (file_exists($info->filename)) { echo 'file exists!'; } ?>`
The above example will output something similar with:
    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!
