How can multiple checkbox values be used for an SQL query in PHP?

To use multiple checkbox values in an SQL query in PHP, you can collect the selected checkbox values in an array and then use the implode function to convert the array into a comma-separated string. This string can then be used in the SQL query with the IN operator to filter the results based on the selected values. 

// Assuming checkbox values are collected in an array called $checkbox_values
$checkbox_values = $_POST['checkbox_values']; // Assuming form is submitted via POST method

// Convert the array into a comma-separated string
$checkbox_string = implode(",", $checkbox_values);

// Use the string in the SQL query with the IN operator
$sql = "SELECT * FROM table_name WHERE column_name IN ($checkbox_string)";
$result = mysqli_query($conn, $sql);

// Process the query result as needed
