Are there any specific security measures to consider when logging database actions in PHP?

When logging database actions in PHP, it is important to consider security measures to prevent any sensitive information from being exposed. One common security measure is to ensure that the log file is stored in a secure location with restricted access permissions. Additionally, it is recommended to sanitize any user input before logging it to prevent SQL injection attacks. Lastly, consider encrypting any sensitive data before logging it to further protect it from unauthorized access. 

<?php
// Ensure log file is stored in a secure location with restricted access permissions
$logFile = '/path/to/secure/logfile.txt';

// Sanitize user input before logging to prevent SQL injection attacks
$userInput = mysqli_real_escape_string($conn, $_POST['user_input']);

// Encrypt sensitive data before logging
$encryptedData = openssl_encrypt($userInput, 'AES-256-CBC', 'secret_key', 0, 'secret_iv');

// Log the database action
file_put_contents($logFile, "User input: $encryptedData\n", FILE_APPEND);
?>
