To make it work escape the / before &.

$output =preg_replace('/&lt;a class=&quot;SForm&quot; class=(.*?)\Ý kiến của bạn&quot; \/&gt;/', '', $output);
                                                                                       ^

You are using / as the regex delimiter and there is a unescaped / in the regex which is being treated as the end delimiter.

You don't need to use regular expressions for something like that...

A much simpler solution would be to use

$output = strip_tags(htmlspecialchars_decode($output));
