What are the potential pitfalls of handling multiple checkbox selections in a search script in PHP?

When handling multiple checkbox selections in a search script in PHP, one potential pitfall is ensuring that the selected values are properly processed and applied to the search query. To solve this issue, you can use an array to store the selected checkbox values and dynamically construct the search query based on these values. 

// Retrieve selected checkbox values
$selectedValues = isset($_POST['checkbox']) ? $_POST['checkbox'] : array();

// Construct the search query based on selected checkbox values
$searchQuery = "SELECT * FROM table WHERE";

foreach ($selectedValues as $value) {
    $searchQuery .= " column = '" . $value . "' OR";
}

$searchQuery = rtrim($searchQuery, ' OR');

// Execute the search query
// Example: $result = mysqli_query($connection, $searchQuery);
