The Apache request_rec struct has many change between version 1.3 and 2.0. perhaps we should rename this fonction in apache2_lookup_uri

for example the byterange has desapear

here is the patch to be more compatible with apache 1.3 version  

PHP_FUNCTION(apache_lookup_uri)
{
        pval **filename;
        request_rec *rr=NULL;

        rr = php_apache_lookup_uri(INTERNAL_FUNCTION_PARAM_PASSTHRU);
        if (!rr)
                WRONG_PARAM_COUNT;

        object_init(return_value);
        add_property_long(return_value,"status", rr->status);
        if (rr->the_request) {
                add_property_string(return_value,"the_request", rr->the_request, 1);
        }
        if (rr->status_line) {
                add_property_string(return_value,"status_line", (char *)rr->status_line, 1);            
        }
        if (rr->method) {
                add_property_string(return_value,"method", (char *)rr->method, 1);              
        }
        if (rr->content_type) {
                add_property_string(return_value,"content_type", (char *)rr->content_type, 1);
        }
        if (rr->handler) {
                add_property_string(return_value,"handler", (char *)rr->handler, 1);            
        }
        if (rr->uri) {
                add_property_string(return_value,"uri", rr->uri, 1);
        }
        if (rr->filename) {
                add_property_string(return_value,"filename", rr->filename, 1);
        }
        if (rr->path_info) {
                add_property_string(return_value,"path_info", rr->path_info, 1);
        }
        if (rr->args) {
                add_property_string(return_value,"args", rr->args, 1);
        }
        if (rr->range) {
                add_property_string(return_value,"range",(char *)rr->range, 1);
        }
        if (rr->boundary) {
                add_property_string(return_value,"boundary",(char *)rr->boundary, 1);
        }
        add_property_long(return_value,"no_cache", rr->no_cache);
        add_property_long(return_value,"no_local_copy", rr->no_local_copy);
        add_property_long(return_value,"allowed", rr->allowed);
        add_property_long(return_value,"sent_bodyct", rr->sent_bodyct);
        add_property_long(return_value,"bytes_sent", rr->bytes_sent);
        add_property_long(return_value,"clength", rr->clength);

#if MODULE_MAGIC_NUMBER >= 19980324
        if (rr->unparsed_uri) {
                add_property_string(return_value,"unparsed_uri", rr->unparsed_uri, 1);
        }
        if(rr->mtime) {
                add_property_long(return_value,"mtime", rr->mtime);
        }
#endif
        if(rr->request_time) {
                add_property_long(return_value,"request_time", rr->request_time);
        }
        ap_destroy_sub_req(rr);
}

What about this patch ?
has someone try it ?
what is the way of apache2 fonction ? 
keep the maximum of backwards compatibility ?

This bug has been fixed in CVS. You can grab a snapshot of the
CVS version at http://snaps.php.net/. In case this was a documentation 
problem, the fix will show up soon at http://www.php.net/manual/.
In case this was a PHP.net website problem, the change will show
up on the PHP.net site and on the mirror sites.
Thank you for the report, and for helping us make PHP better.

I committed a variant of your patch.  Same idea, just done with the existing macros to reduce diff (and code) verbosity.  I had to account for the fact that rr->request_time and rr->mtime are apr_time_t's (microseconds) now rather than time_t's (seconds) as well.  It should now be the case that the only difference between apache 2.0's apache_lookup_uri() and apache 1.3's are the missing byterange and boundary fields (boundary just now disappeared as of 2.0.37).  Is it worth having those in there with wrong (zero) values?  Or should we just leave them out and document that they're gone?  Send me an email if you have an opinion on the matter.  Thanks!
