How can one efficiently handle multiple filters and selections in PHP to improve user experience on a website?

To efficiently handle multiple filters and selections in PHP to improve user experience on a website, you can use arrays to store the filter values and dynamically generate SQL queries based on the selected filters. By doing so, you can easily apply multiple filters without cluttering the code and provide a seamless user experience. 

// Example code snippet to handle multiple filters and selections in PHP

// Define an array to store filter values
$filters = [];

// Check if a filter is selected and add it to the filters array
if(isset($_GET['filter1'])) {
    $filters[] = "column1 = '" . $_GET['filter1'] . "'";
}
if(isset($_GET['filter2'])) {
    $filters[] = "column2 = '" . $_GET['filter2'] . "'";
}

// Generate the SQL query based on the selected filters
$sql = "SELECT * FROM table_name";
if(!empty($filters)) {
    $sql .= " WHERE " . implode(" AND ", $filters);
}

// Execute the SQL query and display the results
$result = mysqli_query($connection, $sql);
while($row = mysqli_fetch_assoc($result)) {
    // Display the results
}
