Use of labels in custom extension

[MarienTimOnline]

Hi there,

How could I use a translation inside a custom extension (bolt 2.2, so older install) ? In twig I can use {{ l('something') }} but I need it in my php-code.

Simply trying the l('something') method in php results in

Error: Call to undefined function Bolt\Extension\TimOnline\Contact\l()

Hope you can help.
