In the provided PHP code for a lottery system, what are the potential issues with the way hits are calculated and displayed for different combinations?

The potential issue with the current code is that the hits for different combinations are not being accurately calculated and displayed. To solve this, we need to ensure that the hits are correctly counted for each combination and displayed accordingly. One way to achieve this is by using an array to store the hits for each combination and then displaying them based on the array values.

// Initialize an array to store hits for each combination
$hits = array();

// Check each combination and calculate hits
foreach ($combinations as $combination) {
    $hits[$combination] = count(array_intersect($combination, $winningNumbers));
}

// Display hits for each combination
foreach ($hits as $combination => $hit) {
    echo "Hits for combination " . implode(", ", $combination) . ": " . $hit . "<br>";
}
