The $ at the end of the expressions makes this translate as "match any
URI that ends on '.php'". So if you request ".../Boards.php/SMS", the
expression doesn't match, because it ends with '/SMS'. That's why the
script doesn't get invoked.

As for how to correct this, you really should look into the
documentation of the application, ideally with some nginx configuration
examples. You can drop the '$' at the end, and then the regex will
match any request that has '.php' somewhere in its URI, but I make no
guarantees to whether this is a good idea, in your case or at all (I
have a hunch it isn't).
