function qode_loading_spinner_wave() {
    $html = '';
    $html .= '<div class="wave">';

}

Above codes is retrieved from a php file that show a loading effect whenever a new page load. I want to add random string from the list by the way in this post: https://stackoverflow.com/a/4730921/4229234

I want to know how to add random string that appear along with the loading effect. I tried to add

$html .= 'echo $randomThings[mt_rand(0,count($randomThings)-1)];';

between main div "wave" tag but it doesn't work. Thanks in advance

If you want to add random after the <div class="wave"> tag, this should work:

$html = '';
$html .= '<div class="wave">';
$random_key = mt_rand(0, count($randomThings) - 1);
$html .= $randomThings[$random_key];
$html .= '<div class="bounce1"></div>';
$html .= '<div class="bounce2"></div>';
$html .= '<div class="bounce3"></div>';
$html .= '</div>';

return $html;
