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); } PatchesPull RequestsHistoryAllCommentsChangesGit/SVN commits

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.hi i am using 5.1 PHP and MYSQL my project is to store images and retrive binary values and convert to an image format again i have inserted the binary values to the feild and i have retrived also but always i am getting the binarys not the image. plesae help me print ("<img src=". $row['bi']."/>");
