How can the PHP code for a lottery system be optimized to enhance accuracy in displaying hits for different combinations and previous draws?

To optimize the PHP code for a lottery system to enhance accuracy in displaying hits for different combinations and previous draws, you can use arrays to store the winning numbers and the player's numbers. Then, you can iterate through the arrays to check for matching numbers and calculate the hits. Additionally, you can implement functions to display the hits for different combinations and previous draws. 

<?php

// Define winning numbers and player's numbers
$winningNumbers = [1, 2, 3, 4, 5];
$playerNumbers = [1, 3, 5, 7, 9];

// Function to calculate hits
function calculateHits($winningNumbers, $playerNumbers){
    $hits = 0;
    foreach($playerNumbers as $number){
        if(in_array($number, $winningNumbers)){
            $hits++;
        }
    }
    return $hits;
}

// Display hits for player's numbers
echo "Hits for player's numbers: " . calculateHits($winningNumbers, $playerNumbers) . PHP_EOL;

// Display hits for different combinations
$combinations = [
    [1, 2, 3, 4, 5],
    [1, 3, 5, 7, 9],
    [2, 4, 6, 8, 10]
];

foreach($combinations as $combination){
    echo "Hits for combination " . implode(", ", $combination) . ": " . calculateHits($winningNumbers, $combination) . PHP_EOL;
}

?>
