php file upload on windows hosting

[tecdesign]

I tried the following script

 

if(is_uploaded_file($_FILES['file']['tmp_name']))
{
// file uploaded to server
move_uploaded_file($_FILES['file']['tmp_name'], "/FILES/$username".$_FILES['form_image']['name']);

}
else
{
print ('<p class="bl"><strong>Unable to upload file.</strong></p><p>');
print_r($_FILES);
print('</p>');
}

 

With no luck, I have no trouble when working with linux hosting using php 4.4 although this is windows hosting using PHP 5
