How can the dimensions (height and width) of an uploaded file be retrieved using PHP's $_FILE array?

To retrieve the dimensions (height and width) of an uploaded file using PHP's $_FILE array, you can use the getimagesize() function. This function returns an array containing the image width and height along with other information. By accessing the width and height values from the returned array, you can retrieve the dimensions of the uploaded file. 

$uploadedFile = $_FILES['file']['tmp_name'];
list($width, $height) = getimagesize($uploadedFile);

echo "Width: " . $width . " pixels<br>";
echo "Height: " . $height . " pixels";
