Valuable isnt working corectly

[TheBW]

I made a script that randomly generates items after fights and then prints out their data so far. But I got this error
When item is generated it is working corectly, but when item isnt generated it throws out this error

Chance: 9399
Hello LVL 100 adventurer!

(test for qlvl - 0)
Itemtype - 0

Warning: Cannot use a scalar value as an array in C:\wamp\www\Game\itemgen.php on line 81
You searched monsters body and found 0 0!

Heres my script

<?php
include ('config.php');
$playerlvl = 100; //Rand (2, 100)-1;
$chance = Rand (0,10000)-1;
$itemstats = array( "strenght", "dexterity", "inteligence", "stamina", "health points", "energy points", "armor rating");
$data = 0;
$quality = 0;
echo "Chance: $chance </br>";
echo "Hello LVL $playerlvl adventurer! </br>";
//Function that generates stats,$playerlvl, $qmulti, $itemstats, $itemtype are stated out of the function
function statgen($playerlvl, $qmulti, $itemstats, $itemtype) {
	$data = array();
    if ($itemtype == "weapon") {
		$data['itemlvl'] = $playerlvl;
        $data['minwdmg'] = round(10 + 3 * $playerlvl * $qmulti/2);
        $data['maxwdmg'] = round(20 + 3 * $playerlvl * $qmulti/2);
        $data['statt1'] = $itemstats[rand(0,6)];
		$data['statt2'] = $itemstats[rand(0,6)];
		$data['stat1'] = round($playerlvl * ($qmulti/2));
		$data['stat2'] = round($playerlvl * ($qmulti/2));
        }
	else {
		$data['itemlvl'] = $playerlvl;
		$data['statAR'] = round($playerlvl * 3/2 + rand(0, 10));
		$data['statt1'] = $itemstats[rand(0,6)];
		$data['statt2'] = $itemstats[rand(0,6)];
		$data['stat1'] = round($playerlvl * ($qmulti/2));
		$data['stat2'] = round($playerlvl * ($qmulti/2));
		}
	return $data;
	}
// Gets itemqlvl, if its=0 than does nothing, else creates item
if ($chance <= 10){
	$itemqlvl = 3;
	}
	elseif ($chance <= 100){
	$itemqlvl = 2;
	}
	elseif ($chance <= 9000) {
	$itemqlvl = 1;
	}
	else {
	$itemqlvl = 0;
	}

echo "</br> (test for qlvl - $itemqlvl) </br>";

switch($itemqlvl){

 if ($itemqlvl >= 1) {
	$itemtypes = array( "weapon", "body", "legs", "feet", "hands", "head");
	$itemtype = $itemtypes[rand(0, 5)];

	}

else {
	$itemtype = 0;
	}
echo "Itemtype - $itemtype <br>";
//Prints out results/tests.

function wprop($data, $quality, $itemtype) {
	$litemtype = $itemtype;
	if ($litemtype == "weapon") {
		if ($data['statt1'] == $data['statt2']) {
			$data['stat'] = $data['stat1'] + $data['stat2'];
			$wprop['stats'] = "Dmg:" .$data['minwdmg']." - " .$data['maxwdmg']." </br>".$data['statt1']." - ".$data['stat']." ";
			}
		else {
			$wprop['stats'] = "Dmg:" .$data['minwdmg']." - " .$data['maxwdmg']." </br>".$data['statt1']." - ".$data['stat1']." </br> ".$data['statt2']." - ".$data['stat2'].".";
			}
		$wprop['type'] = "You searched monsters body and found $quality $itemtype!</br>";
		return $wprop;
		}
	elseif ($litemtype != "weapon") {
		if ($data['statt1'] == $data['statt2']) {
			if ($data['statt1'] == "armor rating") {
				$data['stat'] = $data['statAR'] + $data['stat1'] + $data['stat2'];
				$wprop['stats'] = "Armor rating: ".$data['stat']."";
				}
			else {
			$data['stat'] = $data['stat1'] + $data['stat2'];
			$wprop['stats'] ="Armor: ".$data['statAR']." </br> ".$data['statt1']." - ".$data['stat']."";
				}
			}
		elseif ($data['statt1'] == "armor rating") {
			$data['stat'] = $data['statAR'] + $data['stat1'];
			$wprop['stats'] = "Armor: ".$data['stat']." </br> ".$data['statt2']." - ".$data['stat2']."";
			}
		elseif ($data['statt2'] == "armor rating") {
			$data['stat'] = $data['statAR'] + $data['stat2'];
			$wprop['stats'] = "Armor: ".$data['stat']." </br> ".$data['statt1']." - ".$data['stat1']."";
			}
		else {
			$wprop['stats'] = "Armor: ".$data['statAR']." </br> ".$data['statt1']." - ".$data['stat1']." </br> ".$data['statt2']." - ".$data['stat2']."";
			}
		$wprop['type'] = "You searched monsters body and found $quality $itemtype!</br>";
		return $wprop;
		}
	elseif ($litemtype == 0) {
		$wprop['stats'] = "Monster didn't drop anything";
		$wprop['type'] = "";
		return $wprop;
		}
	}
$wprop = wprop($data, $quality, $itemtype);

echo "".$wprop['type']." ".$wprop['stats']."";
?>
	

I figured that line that isnt working is this one

	elseif ($litemtype == 0) {
		$wprop['stats'] = "Monster didn't drop anything";
		$wprop['type'] = "";
		return $wprop;
		}

But the weard part is that I have defined that $litemtype == 0, it even prints it out on the echo part that i made for testing purpose. Any ideas why this happens?

Edit: I also tried to change $itemtype to "nothing" and NULL in case of nothing beeing dropped, but it didnt fix the problem eather

I would say you are sending a value to wrop() function
that is supposed to be an array. But it is not.

My guess is that $data is not a proper array as is expected in function

$wprop = wprop($data, $quality, $itemtype);
