How do I define a $_POST variable where the field name included a question mark?
<p>One of the fields in my form is
Do You Have a Job Offer?</p>

<p>I have edited the post data into an array $form_data using this code</p>

<pre><code>if (get_magic_quotes_gpc()) {
  $unescaped_post_data = stripslashes_deep($_POST);
} else {
  $unescaped_post_data = $_POST;
}
$form_data = json_decode($unescaped_post_data['data_json']);
</code></pre>

<p>But if I try to set a variable</p>

<pre><code>$job_offer = $form_data-&gt;do_you_have_a_job_offer?[0];
</code></pre>

<p>Using the question mark breaks the script. What is the correct syntax?</p>
