PHP Arrays to set 2 variables

In this code I have a variable set to the Number of the week (1-52) and then a week type. I setup an array that has the week and set the type. I then put the week type variable into an if statement to output that type of week. Now what my problem is... How do I get the array to define the week type with the week number. Looking at the code might make help make more sense out of this.

<?
	$setday = date("l");
	$setweek = date("W"); //GET WEEK NUMBERS
	$a = "Today is an A Day";
	$b = "Today is a B Day";
	$c = "No School Today";
	$d = "Tier 2 of OFYP";
	$e = "Summer Break";
	
	// Week Type:
	// EACH WEEK IS SET TO A CERTAIN TYPE.
	// 1 = ABABA     2 = BABAB     3 = No School All Week     4 = Tier 2     5 = Summer Break
	$week = array(
		 1 => "3",
	 	 2 => "2",
		 3 => "1",
		 4 => "1",
		 5 => "2",
		 6 => "1",
		 7 => "2",
		 8 => "1",
		 9 => "2",
		10 => "1",
		11 => "2",
		12 => "3", //SPRING BREAK
		13 => "1",
		14 => "2", //BAD WEATHER DAY
		15 => "2", 
		16 => "1",
		17 => "2",
		18 => "1",
		19 => "2",
		20 => "1",
		21 => "2",
		22 => "4", //TIER 2
		23 => "4", //TIER 2
		24 => "5", //SUMMER BREAK
		25 => "5", //SUMMER BREAK
		26 => "5", //SUMMER BREAK
		27 => "5", //SUMMER BREAK
		28 => "5", //SUMMER BREAK
		29 => "5", //SUMMER BREAK
		30 => "5", //SUMMER BREAK
		31 => "5", //SUMMER BREAK
		32 => "5", //SUMMER BREAK | LAST WEEK OF JULY
		35 => "5",
		36 => "1", //FIRST WEEK OF SCHOOL
		);
	

	//Set Week Types
	if     ($week == "1" && $setday == "Monday" || "Wednesday" || "Friday") { $day = $a; }	
	elseif ($week == "1" && $setday == "Tuesday" || "Thursday") 			{ $day = $b; }
	elseif ($week == "2" && $setday == "Monday" || "Wednesday" || "Friday") { $day = $b; }	
	elseif ($week == "2" && $setday == "Tuesday" || "Thursday") 			{ $day = $a; }
	elseif ($setday == "Saturday" || "Sunday" || $holiday) 					{ $day = $c; }
	elseif ($week == "3")													{ $day = $c; }
	elseif ($week == "4")													{ $day = $d; }
	elseif ($week == "5")													{ $day = $e; }
	echo $setday . "<br />" . $day; 

?>

I am having a hard time parsing this question. Can you give an example of the outcome you want?

 

Okay so in the array I have 1 through 36 which represent the weeks of the year that i have so far. Each of those weeks is set to a type. So for example type 1 is ABABA. So then when it's that week that type gets put into the if statement below. Then it conforms to that type. So If its Monday, Wednesday, or Thursday then it's an A day and then Tuesday and Thursday are B days. Then the next week it'll be Type 2, and so on. Im not sure how to put the week # and the week type together and put it into the if statement.

 

I still don't really understand what you're saying, but perhaps this is useful:

echo "<p>The type for the current week (#{$setweek}) is: {$week[$setweek]}</p>";
