Functions

mergeRecursive()

Recursively merge multiple documents into a single document.

mergeRecursive(string|array<string|int, mixed>|null $documents) : string

Wraps the ArangoDB AQL function MERGE_RECURSIVE(document1, … documentN). Unlike merge(), sub-documents with the same key are merged recursively rather than replaced wholesale.

Example AQL usage:

MERGE_RECURSIVE({a: {b: 1}}, {a: {c: 2}})   // returns {a: {b: 1, c: 2}}
Parameters
$documents : string|array<string|int, mixed>|null

Multiple documents to merge (at least 2 required).

// Produces: 'MERGE_RECURSIVE(doc1,doc2)'
