The filename (URI) that's being requested.

Return Values

An object of related URI information. The properties of this object are:

  • status
  • the_request
  • status_line
  • method
  • content_type
  • handler
  • uri
  • filename
  • path_info
  • args
  • boundary
  • no_cache
  • no_local_copy
  • allowed
  • send_bodyct
  • bytes_sent
  • byterange
  • clength
  • unparsed_uri

Returns false on failure.

Examples

Example #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 to:

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!

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.

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 :-(.
