php - IF statement not working - Any suggestions?

So I have a function which counts the amount of customer orders.

I want to show a congratulations modal that appears when a customer hits a specific amount of orders.

All of my code is working fine, except when I add this part to the IF statement:

|| in_array($count, $the_digits) && isset( $_COOKIE['tier_advance'] ) && $_COOKIE['tier_advance'] !== $count )

The cookie is being saved properly, and when saved the number is saved as the current value of count. The idea is that the modal will only show if:

A) their current count is in $the_digits array & the cookie is not set. B) their current count is in $the_digits array & the cookie IS set, however the cookies value does not equal their current order $count amount.

This is to prevent the modal showing after the initial display, but still allow it to show again if they hit the next $count amount to move to the next tier.

Can't figure out what is wrong. Or perhaps there is a better way to do this. All help appreciated.

        $the_digits = ['3','5','15','30','50'];

        if ( in_array($count, $the_digits) && !isset( $_COOKIE[ 'tier_advance' ] ) || in_array($count, $the_digits) && isset( $_COOKIE['tier_advance'] ) && $_COOKIE['tier_advance'] !== $count )  {
        echo'
            
            <script>
                    jQuery(window).on("load",function(){
                        jQuery("#tier_advance").modal("show");
                    });
                    jQuery(document).on("click", "#tier_confirm", function(){            
                        // Set a cookie
                        Cookies.set("tier_advance", "' . $count . '", { expires: 356 });
                    });

            </script>
            
            <!-- BEGIN Share Modal -->
            <div class="modal fade" id="tier_advance" tabindex="-1" role="dialog">

ANSWER

$_COOKIE["tier_advance"] !== "$count")

Note the quotations on the variable. Cookies are saved as strings, therefore without the quotations it was ringing true.

Thanks to @mozboz for cleaning it up and making this more apparent for me.

If the problem is with that huge statement with lots of && and || then it's a good idea to simplify it. To refactor your code a bit to make it more understandable (and so you can figure it out you when you look at it in 2 years) you could do something like this:

Before:

    if ( in_array($count, $the_digits) && !isset( $_COOKIE[ 'tier_advance' ] ) || in_array($count, $the_digits) && isset( $_COOKIE['tier_advance'] ) && $_COOKIE['tier_advance'] !== $count )

After:

    $showModal = false;

    if (in_array($count, $the_digits)) {
        if (!isset( $_COOKIE[ 'tier_advance' ] )) {
            $showModal= true;
        } else {
            if ($_COOKIE['tier_advance'] !== $count) {
                $showModal = true;
            } else {
                // echo "false because tier_advance !== count
            }
        } 
    } else {
        // echo "false because not in the_digits";
    }

    if ($showModal) {
          // do the thing
    }

Although this is much longer, it's much easier to understand the logic and it allows you to add some debug statements to it so you can see at what point it set to true/false to debug. I put a couple of echo's in there as examples, but obviously if you can use logging functionality that's better.

EDIT: I just noticed that you're using !== which as you may know does a type check as well as an equality check. I think in this case the cookie might always be a string, so you should try this with just != instead.
