$jsonJoinArray[]
$jsonJoinArray joins the elements of a JSON array into one string, with a separator between two elements — the equivalent of JavaScript’s Array.join(). It is the inverse of $jsonArray. The document is not modified.
Syntax
$jsonJoinArray[key;(...);separator]Parameters
The last argument is the separator; all the arguments before it form the path. At least two arguments are required ($jsonJoinArray[key] is refused). The path is given as separate arguments, one per level (no dot notation: a.b is a single key named a.b). Surrounding spaces are removed and empty arguments are skipped. A whole-number argument selects an element when the current value is an array; otherwise it is used as an object key. At most 100 arguments are accepted in total.
The separator is used as written (, keeps its space) and can be empty. Backslash sequences such as \n are not converted: they stay as two characters.
Return Value
- The elements joined by the separator. Strings, numbers and booleans appear as text, objects and arrays as compact JSON,
nullas an empty string. - An empty string if the value at the path is missing or is not an array.
