Display content if month_tag = Current Month

Hi

I have a PillBox list field called month_tag.  Each of the months are listed.

I would like to display certain content based on the current month of the year. 

The below code works as required. But how do I replace $month_tag = array ('6'); so that this dynamically entered from month_tag:values?

<?php foreach ($promotion_placeholdersRecords as $record): ?>
	
<?php 
$month = date('m');
$month_tag = array ('6');

if (in_array ("$month", $month_tag)){
   echo "<br />June is the month :)";
} else {
   echo "<br />The month is not June";
}
?>
	
<?php endforeach ?>

This is my attempt, but it doesn't work.

<?php foreach ($promotion_placeholdersRecords as $record): ?>
	
<?php 
$month = date('m');
$month_tag = array ($record['month_tag:values']);

if (in_array ("$month", $month_tag)){
   echo "<br />June is the month :)";
} else {
   echo "<br />The month is not June";
}
?>
	
<?php endforeach ?>
