apache_lookup_uri

(PHP 4, PHP 5)

apache_lookup_uriPerform a partial request for the specified URI and return all info about it

Description

object apache_lookup_uri ( string $filename )

This performs a partial request for a URI. It goes just far enough to obtain all the important information about the given resource.

This function is only supported when PHP is installed as an Apache module.

Parameters

filename

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
  • mtime
  • request_time

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!

[method]

[chunked]
[content_type]
[no_cache]
[no_local_copy]
[unparsed_uri]
[uri]
[filename]
[path_info]
[allowed]
[sent_bodyct]
[bytes_sent]
[request_time]

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 :-(.

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.
