What are the potential consequences of not properly securing configuration files in PHP projects?

Improperly securing configuration files in PHP projects can lead to sensitive information being exposed, such as database credentials or API keys. This can result in unauthorized access to databases, services, or systems, leading to potential data breaches or security vulnerabilities. To prevent this, it is essential to store configuration files outside of the web root directory and restrict access to them using proper file permissions. 

// Example of properly securing a configuration file in PHP
$configFile = '/path/to/config.php';

// Check if the configuration file exists and is readable
if (file_exists($configFile) && is_readable($configFile)) {
    // Include the configuration file
    include($configFile);
} else {
    // Handle the error or display a message
    echo 'Error: Configuration file is missing or inaccessible.';
}
