What is the potential issue with using the same name for multiple select boxes in a PHP form?

Using the same name for multiple select boxes in a PHP form can cause conflicts when trying to retrieve the selected values. To solve this issue, you can append square brackets [] to the select box name to make it an array, allowing you to access all selected values as an array in the PHP script. 

<select name="colors[]" multiple>
  <option value="red">Red</option>
  <option value="blue">Blue</option>
  <option value="green">Green</option>
</select>

<select name="sizes[]" multiple>
  <option value="small">Small</option>
  <option value="medium">Medium</option>
  <option value="large">Large</option>
</select>
