For what reason does the layout break?

Question

PHP

Good afternoon, maybe someone came across, my layout breaks when passing an array from php to js using json. The banner breaks, which adjusts to the height of the screen. It begins to stretch down to not normal sizes, and the variables do not intersect anywhere. I don't understand where the ambush can be (

$var = ['a'=>1,'b'=>'2'];
    $var = json_encode($var);
    ?>
    <script>
        let abcd = JSON.parse('<?= $var?>');
        console.log(abcd);
    </script>

There is such an amazing tool. It's called debugger\debugger and is invoked with F12 in most browsers. It is he who will help you, and so it will be an attempt to play vanga.
Nevertheless, Asinguyu, most likely you have data somewhere or an error in the code that you somehow can’t see with your eyes, you can catch this or another bug with the debugger.
