is there anyway to call lambda function with html contents?
<pre><code>function sample($test1, $test2, $inner_html) {
    $html = call_user_func($inner_html);
    echo $test1 .  ' ' . $test2 . ' ' . $html;
}


sample('test1', 'test2', function(){
                    echo 'first test.'
      ?&gt;
       &lt;b&gt;this is a test.&lt;/&gt;
      &lt;?
                    echo 'last test.';
});
</code></pre>
