How can PHP developers ensure that temporary files used for file uploads are properly managed and cleaned up after script execution?

PHP developers can ensure that temporary files used for file uploads are properly managed and cleaned up after script execution by utilizing the `register_shutdown_function` function to register a cleanup function that deletes the temporary files. This ensures that even if the script terminates unexpectedly, the cleanup function will still be executed. 

// Function to delete temporary files
function cleanupTempFiles() {
    foreach (glob('/path/to/temp/files/*') as $file) {
        unlink($file);
    }
}

// Register the cleanup function
register_shutdown_function('cleanupTempFiles');

// Process file uploads here
// After processing, move or copy uploaded files to their final destination
