在子主题中覆盖父主题功能？ 怎么样？

Question

I want to change the output in this function.

function ph_mailchimp($action){
    $msg = get_theme_mod('pic_mailchimp', 'text');
    $output = '
    <div class="newsletter-box well">
      <p>' . $msg  . '</p>
      <form accept-charset="UTF-8" action="'.$action.'" class="new_subscriber" data-remote="true" id="mc-embedded-subscribe-form" method="post">
        <div style="display:none">
          <input name="utf8" type="hidden" value="">
        </div>
        <input class="inputfield" id="mce-EMAIL" name="EMAIL" placeholder="Your email" type="email">
        <input name="subscribe" type="submit" value="Subscribe">
      </form>
    </div>';
    return $output;
}

Basically I want to add a code in my Child theme's functions.php file to override the Output in the function above.

Can anyone help? Thanks.

You can, if you have the proper setup. Install APD from PECL, or runkit from the same. If you have runkit, this should do the trick:

runkit_function_remove ( "ph_mailchimp" );

function ph_mailchimp() {
    echo "Foobar";//do stuff here
}
