How can PHP beginners avoid confusion between gross and net prices when working with arrays of prices?

PHP beginners can avoid confusion between gross and net prices when working with arrays of prices by clearly labeling each price as either gross or net. One way to do this is by using associative arrays with keys like 'gross_price' and 'net_price' to differentiate between the two. This way, when accessing prices in the array, beginners can easily distinguish between the two types of prices. 

// Example of using associative arrays to differentiate between gross and net prices
$prices = [
    'gross_price' => 100,
    'net_price' => 80
];

echo 'Gross Price: $' . $prices['gross_price'] . PHP_EOL;
echo 'Net Price: $' . $prices['net_price'];
