You need to escape the double quotes:

$filters = "library&loc=local,scope:(\"book\")&loc=local,scope:(\"book2\")....";

Alternatively, you can use single quotes for the entire string:

$filters = 'library&loc=local,scope:("book")&loc=local,scope:("book2")....';

Both of these result in the same string which is library&loc=local,scope:("book")&loc=local,scope:("book2")....
