Question

I’m uploading to a 777 permissions folder. The uploads work however the uploaded files have 664 permissions and an ‘Owner’ of ‘nobody’.

How can i change the following scipt to upload files as 777 and set an Owner ?

code comes from Plupload’s upload.php file

if (strpos($contentType, "multipart") !== false) {
    if (isset($_FILES['file']['tmp_name']) && is_uploaded_file($_FILES['file']['tmp_name'])) {
        // Open temp file
        $out = fopen($targetDir . DIRECTORY_SEPARATOR . $fileName, $chunk == 0 ? "wb" : "ab");
        if ($out) {
            // Read binary input stream and append it to temp file
            $in = fopen($_FILES['file']['tmp_name'], "rb");

            if ($in) {
                while ($buff = fread($in, 4096))
                    fwrite($out, $buff);
            } else
                die('{"jsonrpc" : "2.0", "error" : {"code": 101, "message": "Failed to open input stream."}, "id" : "id"}');

            fclose($out);
            unlink($_FILES['file']['tmp_name']);
        } else
            die('{"jsonrpc" : "2.0", "error" : {"code": 102, "message": "Failed to open output stream."}, "id" : "id"}');
    } else
        die('{"jsonrpc" : "2.0", "error" : {"code": 103, "message": "Failed to move uploaded file."}, "id" : "id"}');
} else {
    // Open temp file
    $out = fopen($targetDir . DIRECTORY_SEPARATOR . $fileName, $chunk == 0 ? "wb" : "ab");
    if ($out) {
        // Read binary input stream and append it to temp file
        $in = fopen("php://input", "rb");

        if ($in) {
            while ($buff = fread($in, 4096))
                fwrite($out, $buff);
        } else
            die('{"jsonrpc" : "2.0", "error" : {"code": 101, "message": "Failed to open input stream."}, "id" : "id"}');

        fclose($out);
    } else
        die('{"jsonrpc" : "2.0", "error" : {"code": 102, "message": "Failed to open output stream."}, "id" : "id"}');
}

Most likely you won’t be able to change ownership of the files, as that’d be the user ID the webserver’s running under. You can try, using chown(), though, Most likely you could only change group ownership (using chgrp()). Changing permissions is done via chmod().
