Как использовать и проверить условие <? Php if ($ loggedin):?> If else внутри этого кода javascript для отражения нажатия или нажатия кнопки со стороны сервера?

Я хочу проверить этот '<?php if ($loggedin) : ?>' php, если код условия внутри кода JavaScript, чтобы показать одну из кнопок, выделенных ниже жирным шрифтом в search-box.php, кстати, у меня есть идея сделать это: я могу использовать этот php $ loggedin код за пределами этого js и сохраните переменную js с true или false и, соответственно, я могу показать кнопку, используя переменную js, но я не хочу этого делать, потому что я хочу скрыть код кнопки со стороны клиента, поэтому мне нужно его поместить в php. Я хочу поместить эту кнопку в код result+= js, потому что он будет отображаться как вывод на веб-странице search-box.php при поиске в текстовом поле.
