Answer 1

You can do it like this

$(function(){
    $(".button").on("click",function(){
        $('.ul').append('<li>'+ "<h1>HTML CODE </h1>" + '<?php $array = ["array1", "array2"]; echo("PHP CODE - " . $array[0] ); ?>' + '</li>');
    });
});

*

<button class="button">button</button>
<ul class = "ul"></ul>

Answer 2

You cannot append PHP code in JavaScript. PHP is a server-side language, so it needs to be executed on the server, while JavaSript is executed on the client side (in a user's browser).

So if you append a PHP code, there will be only source code visible to the end user.
