PHPThumb没有生成缩略图为什么会这样？

Question

以下是我的PHP代码：

require_once('phpthumb/phpthumb.class.php');
$phpThumb = new phpThumb();
$output_format = 'jpg';
$image_heights = array(141, 424, 990);
$image_widths = array(100, 300, 700);
$counter = sizeof($_FILES["img"]["tmp_name"]);
$count = 0;
$values = array();

foreach ($_FILES["img"]["tmp_name"] as $array_number => $holding_value)
    {
        $date =  getTime();
        $tmp_img_name = $_SESSION["username"]."_".$date["timestamp"]."."."jpg";

        if(move_uploaded_file($holding_value, $temp."/".$tmp_img_name))
            {
                $phpThumb->resetObject();
                $phpThumb->setSourceFilename($temp."/".$tmp_img_name);
                $phpThumb->setParameter('config_output_format', $output_format);

                if($count == 0)
                    {
                        $phpThumb->setParameter('h', $image_heights[$count]);
                        $phpThumb->setParameter('w', $image_widths[$count]);
                        $phpThumb->setParameter('q', 90);
                        $store_filename = $path1."_".$tmp_img_name;
                    }
                if($count == 1)
                    {
                        $phpThumb->setParameter('h', $image_heights[$count]);
                        $phpThumb->setParameter('w', $image_widths[$count]);
                        $phpThumb->setParameter('q', 90);
                        $store_filename = $path2."_".$tmp_img_name;
                    }
                if($count == 2)
                    {
                        $phpThumb->setParameter('h', $image_heights[$count]);
                        $phpThumb->setParameter('w', $image_widths[$count]);
                        $phpThumb->setParameter('q', 80);
                        $store_filename = $path3."_".$tmp_img_name;
                    }
                if($phpThumb->GenerateThumbnail())
                    {
                        if($phpThumb->RenderToFile($store_filename))
                            {
                                $values[] = $store_filename;
                                // include '../../src/Cloudinary.php';
                                // include '../../src/Uploader.php';

                                // \Cloudinary::config(array
                                //  (
                                //      "cloud_name" => "dczebgs6w",
                                //      "api_key" => "328212291514632",
                                //      "api_secret" => "LvhRA-s59TZ30rPhCieTVx8LzIw"
                                //  ));

                                // $cloudUpload = \Cloudinary\Uploader::upload($store_filename, array("timeout" => 120));

                                // if($cloudUpload)
                            }
                        else
                            {
                                //unable to write file to final destination directory - check folder permissions
                                $message= "Error! Please try again (render).";
                            }
                    }
                else
                    {
                        $message= "Error! Please try again (generate).";
                    }
            }

        $count++;
        unlink($temp."/".$tmp_img_name);
    }
// print_r($values);

代码的问题在于，这一行代码的一切正常工作=＆gt; if(move_uploaded_file($holding_value, $temp."/".$tmp_img_name))我甚至检查过图像是否正在上传，以便在目录中上传。但是，不知怎的，我无法生成thmbnails。为什么这样？

已经在每个循环和每一行检查了我的代码。 Ony临时图像已上传但缩略图未上传。

请帮我这个代码。在此先感谢_ / _
