<?php
global $wpdb;
$results = $wpdb->get_results( "SELECT * FROM wp_postmeta where meta_key = 'fat-mb-boat-toys' AND post_id = $post_id"); // Query to fetch data from database table and storing in $results
if(!empty($results))
    // Checking if $results have some values or not
{    
        echo "<table>";
        echo "<tr>";
        echo "<th> Post ID <th>";
        echo "<th> Meta Key <th>";
        echo "<th> Meta Value <th>";

    foreach($results as $row){
       echo "<tr>";
       echo "<td>". $row->post_id ."<td>";
       echo "<td>". $row->meta_key ."<td>";
       echo "<td>". $row->meta_value ."<td>";
       echo "</tr>";

You would need to first unserialize that data, then you can check the value using print_r to see what you type you are working with and what is available. – Buttered_Toast Commented Feb 18, 2022 at 9:08
can you please provide some reference? – Pardeep Kumar Commented Feb 18, 2022 at 9:30

You should pretty much never need to use $wpdb to grab data. There are helper functions built into WordPress that will do what you need.

In this case, use get_post_meta().

Having used https://www.unserialize.com/ to unserialize your data, it looks like the item list in your question is in $meta['toys_item']['toys_item_ranger']. I'll use that in my code snippet to make a list like the one you're looking for.

$meta = get_post_meta( $post_id, 'fat-mb-boat-toys', true );
if (
    ! empty( $meta )
    && ! empty( $meta['toys_item'] )
    && ! empty( $meta['toys_item']['toys_item_ranger'] ) 
) {
    foreach ( $meta['toys_item']['toys_item_ranger'] as $toy ) {
        echo $toy . '<br />';
    }
}
