Well, yes. You are ritght, "implode" starts with an element.

If it's part of an object. Me question was for the static class tx_div, so
that the function could be called from everywhere. The static varibale has
to exist in the scope of this function. This examples show the use in
functions in instanced classes.

I am not sure if it also would work as expected inside the static class
tx_div.
