How can PHP be used to read and process data from an ini file on a website?

To read and process data from an ini file on a website using PHP, you can use the `parse_ini_file` function to read the contents of the ini file into an associative array. You can then access the values in the array to use them in your PHP code.

// Read the contents of the ini file into an associative array
$config = parse_ini_file('config.ini');

// Access specific values from the array
$database_host = $config['database_host'];
$database_user = $config['database_user'];
$database_password = $config['database_password'];

// Use the values in your PHP code
// For example, connect to a database using the retrieved credentials
$conn = new mysqli($database_host, $database_user, $database_password);
