Join array items

Anatomy

<array:join var="var" var_result="var" delimiter="string" key="string"/>

Description: ARRAY:JOIN joins the items of an array together to form a string representation with each value separated by a given delimiter.

A given key may specify the column of a multidimensional array to join by. If however, the key is omitted, then the array is treated as an unidimensional list.

Attention:

If a key is specified and that key does not exist within the inner array, the corresponding item of the outer array will be skipped.
