如何在foreach循环内划分数组结果？

Question

I have a simple Select query in WordPress PHP, that selects all results from a database table, and I print the results on a page using the basic foreach, shown below:

$newest = $wpdb->get_results("SELECT * FROM wp_refundrequests WHERE state = 'Odottavat' ORDER BY
  request_date DESC", ARRAY_A);
  foreach ($newest as $row) {
   echo "Product names: " . $row['product_name'];
}

My "product_name" column has multiple product names however, since I have inserted them as an array earlier. Here is an example of the data I have in my table:

But I would like to print all of these names on new lines, so the results would be something along the lines of:

Product one 
Product two
Product three

..etc etc, is there a way to do this? I tried to do this with some tags, but that didn't work.

Answer 1

try this way

<?php

    $items = "item1,item2,item3"; // $row['product_name']
    $item = explode(",", $items);
    echo $item[0];

?>

Answer 2

Try this one:

foreach ($newest as $row) {
    $products = explode('","', $row['product_name']);
    foreach ($products as $product) {
        $product = trim($product); // not necessary
        echo "Product name: " . $product . "</br>";
    }
}
