combine 2 comma separated list into one in php

I have 2 arrays that are coming from the database, [options] column has comma-separated values.

Array
(
    [0] => Array
        (
            [id] => 143
            [menu_id] => 590
            [name] => bread
            [options] => small, large
        )

    [1] => Array
        (
            [id] => 144
            [menu_id] => 590
            [name] => jam
            [options] => mango, orange, grape
        )

)

Is there have any way to combine the list of [options] at [0] and [1]?

Example: small, large, mango, orange, grape

Approach

 <?php foreach ($menu_options as $key => $menu_option) : ?>  
     <?PHP $exploded_variant_options = explode(',', $menu_option['options']);
           foreach ($exploded_variant_options as $exploded_variant_option) : ?>
                     <?php echo ucfirst(sanitize($exploded_variant_option)); ?> //print one by one
                             
          <?php endforeach; ?>
  <?php endforeach; ?>
