How can the use of associative arrays in PHP impact performance when accessing object IDs across multiple systems?

Using associative arrays in PHP to store object IDs across multiple systems can impact performance due to the need to iterate through the array to find a specific ID. To improve performance, consider using a database or caching system to store and retrieve object IDs efficiently. 

// Example of using a database to store and retrieve object IDs efficiently
$database = new mysqli("localhost", "username", "password", "database");

// Store object ID
$object_id = 123;
$database->query("INSERT INTO object_ids (id) VALUES ($object_id)");

// Retrieve object ID
$result = $database->query("SELECT id FROM object_ids WHERE id = $object_id");
$row = $result->fetch_assoc();
$retrieved_id = $row['id'];

echo $retrieved_id;
