How to allow uppercase file extensions in photo-uploader?

Im trying to optimize my photo-uploader, so that it'll allow all file-extensions, including uppercase .JPG/.JPEG or .PNG

I've been trying to put strtolower() on the $extension variable, with no luck. And many other solutions, nothing helps. Here's where i filter extension names:

Just installed the exif and mbstrings .dll .. Now i got this error:

"exif_imagetype() filename cannot be empty"

   // FILE EXTENSION FILTER     
   $allowed_types = array(IMAGETYPE_GIF,IMAGETYPE_JPEG,IMAGETYPE_PNG);
   if(in_array(exif_imagetype($_FILES["uploaded_file"]["tmp_name"]), $allowed_types)){
   
         // SUCCSESFUL

Any help is much apreaciated! ive been trying to make this work for hours now :D

Use the strtolower() function for lowercase extension before check;

     // FILE EXTENSION FILTER       
     $allowedExts = array("gif", "jpeg", "jpg", "png");
     $temp = explode('.',$_FILES['uploaded_file']['name']);       
     $extension = end($temp);

                if ((($_FILES["uploaded_file"]["type"] == "image/gif")
                || ($_FILES["uploaded_file"]["type"] == "image/jpeg")
                || ($_FILES["uploaded_file"]["type"] == "image/jpg")
                || ($_FILES["uploaded_file"]["type"] == "image/pjpeg")
                || ($_FILES["uploaded_file"]["type"] == "image/x-png")
                || ($_FILES["uploaded_file"]["type"] == "image/png"))
                && ($_FILES["uploaded_file"]["size"] < 10485760)
                && in_array(strtolower($extension), $allowedExts))
                {
                    // SUCCSESFUL

I have done something very similar on a website I made. Here was my solution.

$file_name = $_FILES['file']['name'];
if ($_FILES['file']['size']>$maxsize) $status = "Error: Picture size too large. Max file     size is $maxsize bytes.<br>";

if (($_FILES['file']['type']!="image/gif") && ($_FILES['file']['type']!="image/pjpeg") && ($_FILES['file']['type']!="image/jpeg") && ($_FILES['file']    ['type']!="image/png")){
$status .= "Error: Wrong file type. Must be JPG or GIF or PNG only.<br>";
}



$picextorg = substr($file_name,-3);
$picext = strtolower($picextorg);

if ((!isset($status)) && ($picext!="gif")&& ($picext!="jpg") && ($picext!="png"))    $status .= "Error: The Wrong file type. Must be JPG or GIF or PNG only.<br> ";

I don't think it would be very hard to implement this with your code. Let me know how it goes!
