How can checkboxes be a better alternative to radio buttons for search functionality in PHP forms?

Checkboxes can be a better alternative to radio buttons for search functionality in PHP forms because they allow users to select multiple options at once, which can be useful for filtering search results based on multiple criteria. To implement checkboxes for search functionality in PHP forms, you can create an array of checkboxes with the same name attribute and use the $_POST superglobal to retrieve the selected values. 

<form method="post" action="search_results.php">
    <input type="checkbox" name="category[]" value="technology"> Technology
    <input type="checkbox" name="category[]" value="fashion"> Fashion
    <input type="checkbox" name="category[]" value="food"> Food
    <input type="submit" value="Search">
</form>

<?php
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    if(isset($_POST['category'])){
        $selected_categories = $_POST['category'];
        // Use $selected_categories array to filter search results
    }
}
?>
