efun: implode

SYNOPSIS:

        string implode(mixed *arr, string del)

DESCRIPTION:

        Concatenate all strings found in array arr, with the string
        del between each element. Only strings are used from the array.

EXAMPLES:

        function                                        returns
        -------------------------------------------------------------------
        implode(({ "foo", "bar", "" }), "*")            "foo*bar*"
        implode(({ "a", 2, this_object(), "c" }), "b")  "abc"

        Together with explode() this can be used as a search and replace
        function of strings:
        implode(explode("a short text", " "), "_")      "a_short_text"

        But nowadays You can also use
        regreplace("a short text", " ", "_", 1)
        instead.
