我能夠綁定 1 個數組作為參數沒問題。但是，我正在嘗試將 2+ 個數組綁定為參數，但效果不是很好。解包后我不斷收到無法使用位置參數的錯誤。如何將數組組合為參數？$query="SELECT price FROM products WHERE status='1'";if(isset($_POST['category'])){    $category_filter = join(',', array_fill(0, count($_POST['category']), '?'));    $sql .= ' AND category IN ('.$category_filter.')';}if(isset($_POST['location'])){    $location_filter = join(',', array_fill(0, count($_POST['location']), '?'));    $sql .= ' AND location IN ('.$location_filter.')';}$stmt = $conn->prepare($query);$stmt->bind_param(str_repeat('ss', count($_POST['category'],$_POST['location'])), ...$_POST['category'],...$_POST['location']);$stmt->execute();$stmt->bind_result($price);
