We Can Store Multiple Select Options on an array and save the values to the database using comma-separated.

<label for="services">Select Services :</label>
          <select id="sel_services" name="services[]" multiple="multiple">
            <option value="engine-oil-change">Engine Oil Change</option>
            <option value="ac-service">AC Service</option>
            <option value="wheel-alignment">Wheel Alignment</option>
            <option value="normal-service">Normal Service</option>
            <option value="body-washing">Body Washing</option>
          </select>
 

processController.php

$service = implode(',', $_POST['services']);
