    Make a string inside your plugin or theme translatable:

    $translated = __( 'Hello World!', 'mytextdomain' );

    ‘mytextdomain’ needs to be a unique text domain used throughout your plugin/theme. This should always be directly passed as a string literal as shown above, not a string assigned to a variable or constant. E.g., this is incorrect:

    $text_domain = 'mytextdomain';
    $string = 'Hello World!';
    $translated = __( $string, $text_domain );

    This seems to work, but it will interfere in automatic parsing of your plugin/theme’s files for translation.
