What are the advantages and disadvantages of using the email address as the unique value for file names instead of uniqid()?

Using the email address as the unique value for file names can make it easier to identify and organize files associated with specific users. However, it can also pose a security risk if the email address is exposed in the file system. On the other hand, using uniqid() generates a random unique identifier that does not reveal any sensitive information, but it may be harder to associate files with specific users. 

// Using uniqid() to generate unique file names
$email = 'example@email.com';
$unique_filename = uniqid() . '_' . $email . '.txt';

// Save file with the unique filename
file_put_contents($unique_filename, 'File content here');
