How can PHP be used to retrieve the original file name of an uploaded file, considering the limitations of the file input element in HTML forms?

When a file is uploaded through an HTML form using the file input element, the original file name is not directly accessible in PHP due to security reasons. However, you can retrieve the original file name by accessing the $_FILES superglobal array, which contains information about the uploaded file, including the original file name.

$originalFileName = $_FILES['file_input_name']['name'];
