What are the advantages and disadvantages of renaming files for security purposes in PHP?

Renaming files for security purposes in PHP can help prevent attackers from guessing or accessing sensitive information by simply knowing the file names. By using random or hashed names for files, it adds an extra layer of security to protect the data stored within them. However, renaming files can also make it harder for developers to locate specific files, especially in larger projects where many files are involved. 

<?php
// Generate a random filename for added security
$random_filename = md5(uniqid(rand(), true)) . '.txt';

// Rename the file using the random filename
rename('original_file.txt', $random_filename);
?>
