PHP PDO MYSQL - 获取与 fetchAll 逗号分隔的数组

Question

我真的卡在这里面了。

我需要像 (138,139,140,141,142,143,144,145) 这样的结果，但我得到的只是一个 (Array,Array,Array,Array,Array,Array,Array,Array)...

我的代码是：

<?php
    try {
                        $dbconn = DBCONNECTION();

                        $sql = "SELECT `product_category_id`, `product_category_parent_id`, `date_available`, `status` 
                                FROM `product_category` 
                                WHERE `product_category_parent_id` = '" . $_GET['cat'] . "' 
                                AND `date_available` <= NOW() 
                                AND `status` = '1' 
                                ORDER BY `product_category_id` ASC";

                        $stmt = $dbconn -> prepare($sql);
                        $stmt -> execute();
                        $array = $stmt -> fetchAll(PDO::FETCH_ASSOC);

                        foreach($array as $row) {
                            $category[] = array($row['product_category_id']);
                        }

                        $subcategory = implode(',', $category);
                        echo $subcategory;
    }
?>

你能帮帮我吗？

非常感谢！

改变

$category[] = array($row['product_category_id']);

对于

$category[] = $row['product_category_id'];
