PHP Save selected options from Multiple Drop Downs to an Array

问题

I have the following code:

<select id='rq1' class='business' name='q1'>
  <option value='1'>1</option>
  <option value='2'>2</option>
</select>
<select id='rq2' class='business' name='q1'>
  <option value='1'>1</option>
  <option value='2'>2</option>
</select>
<select id='rq3' class='business' name='q1'>
  <option value='1'>1</option>
  <option value='2'>2</option>
</select>

What I am trying to understand is if it is possible to save the responses from each of the dropdowns to an Array. The reason for this is so that I can save the results into one column in the database as opposed to having a column for each dropdown response. Does that make sense?

Is this possible, is it as straightforward as adding [] to the name and then unserializing them to post to the database?

Do you mean

<?php
    var_dump($_POST);
?>
<form method='post'>
    <select id='rq1' class='business' name='q1[]'>
      <option value='1'>1</option>
      <option value='2'>2</option>
    </select>
    <select id='rq2' class='business' name='q1[]'>
      <option value='1'>1</option>
      <option value='2'>2</option>
    </select>
    <select id='rq3' class='business' name='q1[]'>
      <option value='1'>1</option>
      <option value='2'>2</option>
    </select>
    <input type='submit'>
</form>

When you submit the form, you will get data in Array.
