What are best practices for preserving the original file name and extension during file uploads in PHP?

When uploading files in PHP, it is important to preserve the original file name and extension to maintain the integrity of the uploaded file. To achieve this, you can use the $_FILES superglobal array to access the original file name and extension, and then use move_uploaded_file() function to save the file with the original name. 

$originalFileName = $_FILES['file']['name'];
$extension = pathinfo($originalFileName, PATHINFO_EXTENSION);
$uploadDirectory = 'uploads/';
$newFileName = $uploadDirectory . $originalFileName;

move_uploaded_file($_FILES['file']['tmp_name'], $newFileName);
