I am experimenting with the date and in_array functions of PHP.

Based on what I have read in the manual I can't understand why my code is returning the else part of the if statement. If the date('D') is returning Tue why doesn't it run the if part?

<?php

date_default_timezone_set('UTC');

$weekdays = array("Mon", "Tue", "Wed", "Thur", "Fri", "Sat", "Sun");

$today = date('D');

if(in_array("Mon", "Tue", "Wed", "Thur", "Fri", $weekdays) == $today)
   {
         echo "It's" . " ";
         echo $today;
         echo " " . "Get out of bed and go to work";
    }else{
         echo "Do whatever you want becuase it's" . " ";
         echo $today;
};
?>

I've tried various things and and changed the if part to this, but to no avail.

if(in_array(array("Mon", "Tue", "Wed", "Thur", "Fri"), $weekdays) == $today)

Can someone tell me what is wrong with the syntax?

The in_array function checks if a value exists in an array, returning true or false.

If you want to know if $today is a weekday, you would want to do something like:

$weekdays = array("Mon", "Tue", "Wed", "Thur", "Fri");
if(in_array($today, $weekdays)) {
   ...
}

    }else{
         echo "Do whatever you want becuase it's" . " ";
         echo $current_day;
};
