如何在不插入php中的每个循环的情况下将数组插入数据库

Question

I have this array from the checkbox

<?php
    $query = $handler->query("SELECT * FROM colors");
    while ($row = $query->fetch()) {?>
 <input type="checkbox" name="check_list[]" id="<?php echo $row['id']?>" value="<?php echo $row['hex'];?>">
<?php } ?>

PHP Query

<?php
    if(!empty($_POST['check_list'])) {
    foreach($_POST['check_list'] as $check) {
    $query = $handler->query("INSERT INTO images (color_tags) VALUES ('$check')");
        }
    }
        ?>

I want to insert the data's from the array without inserting it on every row I want it to be just separated in commas like data1,data2,data3 then insert it.

Answer 1

Store it in json.

json_encode($array)

<?php
if(!empty($_POST['check_list'])) {

$query = $handler->query("INSERT INTO images (color_tags) VALUES ( json_encode($_POST['check_list']))");

}
?>
