php - Problems using in_array and date in if/else -

I am using PHP functions and experiments.

I personally do not understand that my code is refunding the second part of the statement. If is returning the date ('D') Tue , why does not he run that part?

  & lt; Php date_default_timezone_set ('UTC'); $ Weekdays = array ("Mon", "Mars", "Mercury", "Thunder", "Venus", "Saturn", "Sun"); $ Today = Date ('D'); If (in_array ("Mon", "Mars", "Mercury", "Thunder", "Venus", $ Weekdays) == $ Today) {Echo "This is" ""; Echo today $; Echo "" "Get out of bed and go to work"; } Else {dungo "do whatever you want"; Echo today $; }; ? & Gt;   
 I have tried many things and changed  if  to it, but there is no benefit.  
  if someone can tell me what is wrong with syntax?   
 < Div class = "post-text" itemprop = "text"> 
  in_release  function.  
 If you want to know if  $ today  There is a weekday, you want to do something like this:  
  $ weekdays = array ("Mon", "Mars", "Mercury", "Thunder", "Venus"); If (in_array ($ Today, $ Weekdays)) {...}
