"Amusingly" enough, the array_reduce method didn't work for PHP5. I
guess that makes sense though.
-- Oh don't worry, I'm having lots of fun (on my own) in my own little
thread already.

I was adding support for PHP4 to the script, which made me wonder: if
binary arrays are meant to be received like this, what would be the
fastest way to reformat them?
foreach ($content As $obj) {
// or foreach($content->value As $obj) in PHP4
$image .= chr($obj);
}
echo($image);
or maybe something like
function rchr($v, $w) {
$v .= chr($w);
return($v);
}
$image = array_reduce($content, rchr);
// or $image = array_reduce($content->value, rchr); in PHP4
or something else?
Thanks.

FYI, source of a now-operational version here:
http://demis.inny.org/temp/wms_working.php.txt
Non-operational script as .phps file:

Description:
------------
I was translating the following script:
http://demis.inny.org/temp/wms.asp.txt
http://demis.inny.org/temp/wms.php.txt is a non-functional translation
I had at that time.
If $QueryString ($_SERVER['QUERY_STRING']) contained the proper
variables/values, the WMSServer would return a
byte-stream/array/whatever (I'm no genius at COM and such) containing a
map-image.
http://demis.inny.org/temp/wms.php.txt would return, instead of the
image, 8 question marks (????????). I solved this by changing
echo($content); into the following:
if (substr($contenttype, 0, 5) == 'image') {
$image = null;
foreach ($content As $obj) { // $obj will contain 1 byte each time,
echo'ing it would print a decimal which in turn represents an ASCII
value. hence chr();
$image .= chr($obj);
}
echo($image);
} else {
echo($content);
}
But this doesn't seem too resource-efficient to me (a run of foreach
for every byte), and I doubt it's an intended work-around (the ?'s
really got me puzzled, I'd have expected an error message).
Anyway, seeing as I needed to use chr(); with foreach, this seems
related to a fixed bug #15782: http://bugs.php.net/bug.php?id=15782
Maybe you were aware of all of this.. Maybe not. Cheers.
Reproduce code:
---------------
$WMSService = new COM("DemisWMSConnect.Service");
$MapServer = $WMSService->WMS($wms);
if (!is_object($MapServer)) {
dosomestuffand();
die();
} else {
$content = new VARIANT(null);
$contenttype = new VARIANT(null);
$return = $MapServer->WMSRequest($QueryString, $content,
$contenttype);
header('Content-type: '.$contenttype);
echo($content);
}
