How can deprecated comments in configuration files impact PHP scripts?

Deprecated comments in configuration files can impact PHP scripts by causing confusion and potential errors during execution. It is important to remove or update deprecated comments to ensure that the configuration settings are accurately reflected in the PHP scripts. 

// Before fixing deprecated comments
$config = [
    // Database settings
    'db_host' => 'localhost',
    'db_user' => 'root',
    'db_pass' => 'password',
    // Deprecated comment: use db_name instead of dbname
    'dbname' => 'my_database'
];

// After fixing deprecated comments
$config = [
    // Database settings
    'db_host' => 'localhost',
    'db_user' => 'root',
    'db_pass' => 'password',
    'db_name' => 'my_database'
];
