concatSeparator()

Concatenate strings using a separator.

concatSeparator([string $separator = Char::EMPTY ][, array<string|int, mixed>|string|null $arguments = null ]) : string

This helper wraps the ArangoDB AQL function CONCAT_SEPARATOR(separator, value1, value2, ... valueN) which concatenates multiple values into a single string using the specified separator between each value.

Example AQL usage:

CONCAT_SEPARATOR(", ", "a", "b", "c")     // returns "a, b, c"
CONCAT_SEPARATOR(" - ", doc.first, doc.last)  // returns "John - Doe"
CONCAT_SEPARATOR("", "a", "b", "c")       // returns "abc" (no separator)
Parameters
$separator : string = Char::EMPTY

The separator string to use between values.

$arguments : array<string|int, mixed>|string|null = null

An AQL string expression or an array of AQL values.
