What are the differences between using the Standard PHP Library and arrays for data structures in PHP?

When working with data structures in PHP, using the Standard PHP Library (SPL) provides a more robust and efficient way to manipulate arrays and other data types. SPL offers a variety of built-in data structures and algorithms that can simplify common tasks such as sorting, filtering, and iterating over data. In comparison, using traditional arrays for data structures may require more manual coding and may not offer the same level of performance and functionality. 

// Example of using SPL to work with data structures
$queue = new SplQueue();
$queue->enqueue('first');
$queue->enqueue('second');
$queue->enqueue('third');

while (!$queue->isEmpty()) {
    echo $queue->dequeue() . PHP_EOL;
}
