What are some best practices for sorting and filtering data in PHP using buttons or checkboxes?

When sorting and filtering data in PHP using buttons or checkboxes, it is important to handle the user input properly to ensure security and accuracy. One common approach is to use conditional statements to determine how the data should be sorted or filtered based on the user's selection. This can be achieved by setting up different functions or queries that are triggered by the user's input. 

// Example code for sorting and filtering data in PHP using buttons or checkboxes

// Assuming $data is an array of data to be sorted and filtered

// Check if a sorting option is selected
if(isset($_GET['sort'])){
    $sortOption = $_GET['sort'];

    // Sort the data based on the selected option
    if($sortOption == 'asc'){
        sort($data);
    } elseif($sortOption == 'desc'){
        rsort($data);
    }
}

// Check if a filtering option is selected
if(isset($_GET['filter'])){
    $filterOption = $_GET['filter'];

    // Filter the data based on the selected option
    if($filterOption == 'even'){
        $data = array_filter($data, function($value){
            return $value % 2 == 0;
        });
    } elseif($filterOption == 'odd'){
        $data = array_filter($data, function($value){
            return $value % 2 != 0;
        });
    }
}

// Display the sorted and filtered data
foreach($data as $value){
    echo $value . "<br>";
}
