What are the potential pitfalls when transferring data from a temporary CSV file to a permanent one in PHP?

When transferring data from a temporary CSV file to a permanent one in PHP, potential pitfalls include not properly handling errors during the transfer process, overwriting existing data unintentionally, and not closing the files properly after the transfer is complete. To solve these issues, you should implement error handling, check for existing files before overwriting them, and ensure that files are closed after the transfer. 

<?php

$sourceFile = 'temp.csv';
$destinationFile = 'permanent.csv';

if (file_exists($destinationFile)) {
    // Handle existing file, e.g., prompt user to confirm overwrite
}

if (!copy($sourceFile, $destinationFile)) {
    // Handle copy error, e.g., display an error message
} else {
    unlink($sourceFile); // Remove temporary file after successful transfer
}

?>
