Creating Store Clock Function - Open/Close & Events depending on time - php

Question

So I have a code that is functioning properly. I received some help putting this together because despite feeling reasonably confident in my coding skills (fairly new) - time avoids me, I find it confusing to determine how it works in PHP.
I am looking to create a function that acts as my stores clock and returns "open" - "closed" - "1 hour to close" results that I can use in other functions.
For example:
if ( store_clock() == 'open' ) {
echo 'Open';
}
elseif ( store_clock() == '1_hr_left' ) {
echo 'You have 27 mins and 12 secs to place an order' );
else {
echo 'Sorry, we are closed.';
}
I currently have the following code which works correctly in regard to closing times, properly displaying the time left countdown etc. The issue being I don't have my open times, and I would prefer to split the code up - allowing me to use the store_clock() function to trigger other events throughout the site... not just the closing counter.
To do this I am assuming I would need 2 to 3 different functions, rather than just the 1... however I am feeling very confused. Any help appreciated. (PS. get_field() is calling ACF values)
function sat_clock() {
$the_time = current_time('timestamp');
$exact_time = gmdate('g:ia', $the_time);
$weekday_close = get_field('weekday_close', 'options');
$sat_close = get_field('sat_close', 'options');
$sun_close = get_field('sun_close', 'options');
// Set your closing times here from sun-sat
$closing_times = array( $sun_close, $weekday_close, $weekday_close, $weekday_close, $weekday_close, '7:31 pm', $sat_close );
if ( $closing_times[date( 'w', current_time('timestamp') )] !== false ) {
$closing_time = strtotime( sprintf( '%s %s', date( 'd F Y', current_time('timestamp') ), $closing_times[date( 'w', current_time('timestamp') )] ) );
if ( $closing_time - current_time('timestamp') > 0 && $closing_time - current_time('timestamp') < 1800 ) {
echo '<strong>LAST CALL</strong><p class="m-0" id="closing-soon-timer"></p>';
?>
<script>
var timeLeft = <?php echo $closing_time - current_time('timestamp'); ?>;
// Update the count down every 1 second
var x = setInterval(function() {
// Time calculations for minutes and seconds
var minutes = Math.floor(timeLeft / 60);
var seconds = Math.floor(timeLeft % 60);
// Display the result in the element with id="demo"
document.getElementById("closing-soon-timer").innerHTML = "You have <strong>" + minutes + "</strong> minutes " + "<strong>" + seconds + "</strong> seconds to place an order.";
// If the count down is finished, write some text
if (timeLeft < 0) {
clearInterval(x);
document.getElementById("closing-soon-timer").innerHTML = "Closed for today";
}
timeLeft--;
}, 1000);
</script>
<?php
} elseif ( $closing_time - current_time('timestamp') < 0 ) {
echo "<p>Closed for today</p>";
} else {
echo "<p>Opened</p>" . gmdate('g:ia', $closing_time);
var_dump($exact_time);
}
} else {
echo "<p>Closed for today</p>";
}
}
