Marriage visitor visa is just that......it's a visit visa for those folks who only want to visit UK for the purpose of getting married. After the marriage they return home.
It's not a Fiancée visa

If you want to settle here in UK it doesn't matter whether you want to get married in UK as a Fiancée or get marry in Philippines you'll need to follow the same application form and requirements process.

As a first step in reviewing the forms and documentation take a look at the UKVI webpage - Apply to join family living permanently in the UK

Take a look at the application form details here - Application for UK visa for family settlement: form VAF4A then ask any specific questions.

If you haven't already searched here in the forum look here to get some additional background info - How to apply for a spouse visa

Hope this helps
