How can PHP be used to generate and manage client secrets for authentication purposes?

To generate and manage client secrets for authentication purposes in PHP, you can use the random_bytes() function to generate a secure random string of bytes and then encode it in base64 to create a client secret. This secret can be stored securely in a database or configuration file and used for authentication when needed.

// Generate a random client secret
$clientSecret = base64_encode(random_bytes(32));

// Store the client secret securely (e.g., in a database or configuration file)
// Use $clientSecret for authentication purposes
