Are there any potential pitfalls in securing PHP source code?

One potential pitfall in securing PHP source code is leaving sensitive information, such as database credentials or API keys, hardcoded within the code. To solve this issue, it is recommended to store sensitive information in environment variables or configuration files outside of the web root directory. 

// Store sensitive information in environment variables
$host = getenv('DB_HOST');
$username = getenv('DB_USERNAME');
$password = getenv('DB_PASSWORD');
$database = getenv('DB_NAME');

// Connect to the database using the stored credentials
$conn = new mysqli($host, $username, $password, $database);
