What are some alternative file formats that can be used to store data more efficiently and securely than a plain text file in PHP?

Storing sensitive data in plain text files in PHP can pose security risks as the information can be easily accessed if the file is compromised. To store data more efficiently and securely, alternative file formats such as JSON, XML, or encrypted files can be used. These formats provide better data organization, structure, and encryption to protect sensitive information. 

// Example of storing data in a JSON file
$data = ['username' => 'john_doe', 'password' => 'securepassword123'];
$jsonData = json_encode($data);
file_put_contents('data.json', $jsonData);

// Example of storing data in an encrypted file
$encryptedData = openssl_encrypt(json_encode($data), 'AES-256-CBC', 'secretkey', 0, '16charIV');
file_put_contents('data.enc', $encryptedData);
