                    isArray(string $value) : string

This helper wraps the ArangoDB AQL function IS_ARRAY() and returns a string representation of the corresponding expression.

The AQL function IS_ARRAY(value) evaluates to true if the provided value is an array (either a list or an object array), and false otherwise.

Example output:

IS_ARRAY(doc.tags)

example

use function oihana\arango\db\functions\isArray;

$expr = isArray('doc.tags');
// Produces: 'IS_ARRAY(doc.tags)'
