Unless she can prove to the ECO that there are reasons why she will return back to the Philippines there's a good chance that she wil be refused.

By reasons it usually mean showing that she owns property, or having a good job. Having a British boyfriend actually seems to help too as it is seen as a reason to return to the Philippines (less likely to overstay when you can legally get visas...).
