Wildcards

Wildcards allow you to match multiple items in arrays and collections using the * symbol. They work across all Data Helpers classes and enable powerful bulk operations.

Basic Wildcard Usage

Use * to match any single segment at that position:

$data = [
    'users' => [
        ['name' => 'Alice', 'email' => 'alice@example.com'],
        ['name' => 'Bob', 'email' => 'bob@example.com'],
    ],
];

$accessor = new DataAccessor($data);
$emails = $accessor->get('users.*.email');

Deep Wildcards

Multiple * can appear in one path:

$skus = $accessor->get('orders.*.items.*.sku');

Wildcard Operators

Use SQL-like operators with wildcards:

• WHERE - Filter items
• ORDER BY - Sort items
• LIMIT/OFFSET - Pagination
• GROUP BY - Aggregations
• DISTINCT - Remove duplicates

See DataMapper for detailed examples.
