$ini_array = parse_ini_file("config.ini"); echo $ini_array['database_name'];
$config_data = [ 'database_name' => 'my_database', 'database_user' => 'root', 'database_password' => 'password123' ]; $config_file = fopen("config.ini", "w"); foreach ($config_data as $key => $value) { fwrite($config_file, "{$key}={$value}\n"); } fclose($config_file);In this example, we are creating a new configuration file named "config.ini" and writing the contents of an associative array to it. Each key-value pair is written in the format of "key=value". Package Library: Standard PHP Library (SPL) Overall, PHP file config is a useful library for managing configuration files in PHP.
