What are the advantages and disadvantages of using arrays and loops in PHP for analyzing stock market data?

When analyzing stock market data in PHP, using arrays and loops can be advantageous as they allow for efficient storage and manipulation of data. Arrays can store multiple data points such as stock prices, volumes, and timestamps, while loops can iterate through the array to perform calculations or comparisons. However, using arrays and loops can also be disadvantageous as they may consume more memory and processing power, especially when dealing with large datasets. 

// Sample PHP code using arrays and loops to analyze stock market data

// Sample array of stock prices
$stockPrices = [100.50, 102.75, 98.20, 105.30, 99.80];

// Calculate the average stock price using a loop
$total = 0;
foreach ($stockPrices as $price) {
    $total += $price;
}
$averagePrice = $total / count($stockPrices);

echo "Average stock price: $averagePrice";
