I'm bit confused about the meaning of this line:
$show_title = Ninja_Forms()->form( $form_id )->get_setting( 'show_title' );
Is -> available in PHP, or it used only within WordPress.

NO -> is not wordpress specific, it is object operator in php.
When you want to call a method of an instance then you call the method with ->
Class SomeClass{
function example(){
return 'This is an example function'
}
}
$obj = new SomeClass();
$obj->example(); // we are calling example function with -> operator
Additional Info: there is one more operator :: which is used to call for static methods of a class.

Also show an example the process of accessing this $show_title = Ninja_Forms()->form( $form_id )->get_setting( 'show_title' ); – Menon Jats Nov 27 '15 at 11:13

Ninja_Forms()->form( $form_id )->get_setting( 'show_title' );Ninja_Forms()is a function which returns an object instance. so calling an method of it isform($form_id)and now this too returns an object instance. finally calling the methodget_setting('show_title');– WPTC-Troop Nov 27 '15 at 11:27 -
Nice. can you write a small program using this above for better understanding. – Menon Jats Nov 27 '15 at 11:48
