Move_uploaded_file() function working on Linux server but not on Windows server

Question

I am having an issue. I created a form from where people can apply for jobs. I have 3 fields where I allow users to upload resume, references and other materials. This form works perfectly on my server which is linux based. When I uploaded it to a windows server, I get the following errors:

Warning: move_uploaded_file(./application/D:\Temp\php\php945C.tmp_tumblr.png) [function.move-uploaded-file]: failed to open stream: Invalid argument in D:\Hosting\9664396\html\application.php on line 23
Warning: move_uploaded_file() [function.move-uploaded-file]: Unable to move 'D:\Temp\php\php945C.tmp' to './application/D:\Temp\php\php945C.tmp_tumblr.png' in D:\Hosting\9664396\html\application.php on line 23

Any help would be appreciated.

Here is the code:

if(isset($_FILES["photoToUpload"]['name'])){
        $original_img_name = $_FILES["photoToUpload"]['name'];
    } else {
        $original_img_name = "";
    }

    $the_photo_url="None Uploaded";
    if($original_img_name != ""){
        $target = './application/';

        $img_name = str_replace("&", "and", $original_img_name);
        $img_name = preg_replace('/[^.a-zA-Z\d\s]+/s', '', $img_name);
        $img_name = str_replace('  ', ' ', $img_name);
        $img_name = str_replace(' ', '_', $img_name);
        $img_name = str_replace("/", "", $_FILES["photoToUpload"]['tmp_name']) . "_" . $img_name;

        move_uploaded_file($_FILES["photoToUpload"]['tmp_name'], $target . $img_name);
        $the_photo_url = $target . $img_name;
    }

This code is working perfect on my host which is linux based.

下一行是错误的，应在将tmp_name添加到$ img_name时将其删除。

$img_name = str_replace("/", "", $_FILES["photoToUpload"]['tmp_name']) . "_" . $img_name;
