What potential pitfalls should be considered when using timestamps in file names with PHP?

When using timestamps in file names with PHP, one potential pitfall to consider is that timestamps can be easily manipulated or duplicated, leading to potential conflicts or security vulnerabilities. To mitigate this risk, consider using a combination of a timestamp and a unique identifier, such as a random string or a hash, in the file name to ensure uniqueness and prevent tampering. 

$timestamp = time();
$unique_id = uniqid();
$file_name = $timestamp . '_' . $unique_id . '.txt';
// Use $file_name in your file operations
