What are the potential pitfalls of working with arrays containing a large number of entries in PHP?

Working with arrays containing a large number of entries in PHP can lead to performance issues due to increased memory consumption and slower processing times. To mitigate this, consider using pagination or limiting the number of entries fetched at a time to improve performance. 

// Example of limiting the number of entries fetched at a time
$entries = []; // large array containing entries
$limit = 100; // limit the number of entries fetched at a time

for ($i = 0; $i < count($entries); $i += $limit) {
    $chunk = array_slice($entries, $i, $limit);
    
    // Process $chunk entries here
}
