The filter |implode applies to an array.

The |implode filter is used to join array elements into a string. The elements are glued by a separator.

For example, from [(#SET{my_table, #ARRAY{cle1, 1999, cle2, 12, cle3, 31}})], [(#GET{my_table}|implode{-})] will return: "1999-12-31"

-  if the separator is the comma character, it should be enclosed in single quotes:
[(#GET{my_array}|implode{', '})]
-  To make the filter more convenient to use in templates, |implode reverses the writing of the PHP function of the same name.
