Functions

concat()

Concatenate multiple values into a single string.

concat(array<string|int, mixed>|string|null $arguments) : string

This helper wraps the ArangoDB AQL function CONCAT(value1, value2, ... valueN) which concatenates multiple values into a single string. Values are automatically converted to strings during concatenation.

Example AQL usage:

CONCAT("Hello", " ", "World")     // returns "Hello World"
CONCAT(doc.firstName, " ", doc.lastName)  // concatenates name parts
CONCAT("ID: ", doc._key)          // returns "ID: 123"
Parameters
$arguments : array<string|int, mixed>|string|null

An AQL string expression or an array of AQL values.
