UCE Docs / array_merge

Signature

StringMap array_merge(StringMap a, StringMap b)
DValue array_merge(DValue a, DValue b)

Parameters

a : left-hand source map or tree
b : right-hand source map or tree
return value : merged result

Merges two maps or trees using PHP-like merge behavior.

For StringMap, keys from b overwrite keys from a.

For DValue, string keys from b overwrite keys from a. Numeric keys are appended and reindexed when either side behaves like a list.

This helper is the closest UCE equivalent to PHP array_merge() for common request, config, and JSON-shaped data.

Example

StringMap left;
left["name"] = "Ada";
StringMap right;
right["role"] = "admin";
StringMap merged = array_merge(left, right);
print(merged["name"], " ", merged["role"], "\n");
Output
Ada admin
