Can combining stdClass objects in PHP lead to any performance implications or memory usage concerns?

Combining stdClass objects in PHP can lead to increased memory usage and potential performance implications, especially when dealing with large datasets. To mitigate this, consider using arrays instead of stdClass objects for combining data. Arrays are more memory-efficient and perform better when merging or manipulating data structures in PHP.

// Using arrays instead of stdClass objects for combining data
$object1 = ['key1' => 'value1', 'key2' => 'value2'];
$object2 = ['key3' => 'value3', 'key4' => 'value4'];

$combinedArray = array_merge($object1, $object2);
