I found solution:

--- 
environment: development
classes: 
    php: 
        source_dir: "${domain}"
init.pp

class php (
  $source_dir          = params_lookup( ''source_dir'' ),
) {


   $conf = regsubst($php::source_dir, ''\$\{'',
''#{'', ''G'')
   $conf1 = inline_template("<%= %Q($php::conf) %>"
    notify{"test $php::conf1":}

}

output:

Notice: test fabrik.test
