Are there any best practices for implementing a counter for different options in a form in PHP?

When implementing a counter for different options in a form in PHP, one best practice is to use an associative array to store the count of each option selected by the user. This allows for easy tracking and updating of the counts for each option. Additionally, using sessions or cookies can help persist the count data across multiple form submissions. 

// Initialize an associative array to store the count of each option
$optionsCount = [];

// Check if form is submitted
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    // Get the selected option from the form
    $selectedOption = $_POST['option'];

    // Update the count for the selected option in the associative array
    if (array_key_exists($selectedOption, $optionsCount)) {
        $optionsCount[$selectedOption]++;
    } else {
        $optionsCount[$selectedOption] = 1;
    }
}

// Display the counts for each option
foreach ($optionsCount as $option => $count) {
    echo "Option $option: $count<br>";
}
