How can PHP variables be properly assigned when retrieving form data for file storage?

When retrieving form data for file storage in PHP, it's important to properly assign variables to ensure the data is handled correctly. This can be done by using the $_FILES superglobal array to access the uploaded file data and assign it to variables for processing and storage. Make sure to check for errors and validate the file before moving it to a desired location on the server. 

if ($_SERVER["REQUEST_METHOD"] == "POST") {
    $file = $_FILES["file"];
    
    $fileName = $file["name"];
    $fileTmpName = $file["tmp_name"];
    $fileSize = $file["size"];
    $fileError = $file["error"];
    $fileType = $file["type"];
    
    // Validate and process the file data
}
