#34253 [NEW]: COM binary object/array issue (question marks?)

From: inny at core dot fetchnet dot org Operating system: Windows 2000 PHP version: 5.1.0RC1 PHP Bug Type: COM related Bug description: COM binary object/array issue (question marks?) 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.
