php - Silent failure on move_uploaded_file and ZipArchive::Close -

update/possible solution: i've realized files being moved c:\windows\temp invisible due file permissions. if try access files via browser, 401 error. believe these files retaining original permissions , unable see them or mess them via php/browser. option change c:\windows\temp folder permissions or move default_upload_folder within wwwroot chain.

i have iis7 server running php script accepts $_files, move_uploaded_file add files directory , zips files using ziparchive.

both of these statements failing.

here code logic:

ini_set('display_errors',1);  if(!empty($_files)){     $tempfile = $_files['filedata']['tmp_name'];    $targetpath = 'c:\\inetpub\\wwwroot\\sitename\\design\\uploads\\';    $targetfile = $targetpath.$_files['filedata']['name'];     $zip_file = $targetpath . htmlspecialchars($_post['session_id']) . '.zip';     move_uploaded_file($tempfile, $targetfile);     $zip = new ziparchive;    $res = $zip->open($zip_file, ziparchive::create);    $zip->addfile($tempfile, $_files['filedata']['name']);    $zip->close();  } 

$tempfile , $targetpath show having 0777 permissions when check them within script.

move_uploaded_file shows no error , returns true, errors if use different directory. appears directory correct. code fails move file new directory. there no error message if use try...catch.

none of ziparchive code fails until $zip->close(), returns false. there no error message if use try...catch.

the code worked on wamp test environment. code running script c:\inetpub\wwwroot\sitename\design\uploadify\uploadify.php.

$_files has correct data based on var_dump. $tempfile resolves c:\windows\temp\php___.tmp. have feeling may issue lies, don't know how address it.

check if have doc_root setting in php.ini poinitng proper directory. should specify upload_tmp_dir (in file uploads section; subfolder of doc_root awesome) make sure different system default.
