Fxmanifest doesn't read php files as ui_page


I’m developing my own UI, but I’m having a problem with fxmanifest not reading a .php file in ui_page.
Am I doing something wrong or simply can’t put php files in it?

My fxmanifest.lua file

fx_version 'cerulean'
game 'gta5'

author 'PBoinaJP'
description 'My Own UI'
version 'beta'

ui_page 'UI/index.php'

files {


client_scripts {


server_script 'server/**.lua'

Thanks for reading!

PHP files need to be processed from a server. Browsers don’t support PHP.
