Check ID of tiles around player

Hello! I'm here for a small function that I need, it will check for the 8 tiles around a player (and the tile below the player making it 9 tiles) and check if their ID is equal to a specific ID.

I (think that I) can make it but I need it to be efficient because my script is huge.

This is a small example of the tiles it's supposed to check and the tile that the player is standing on.

This is an example of the function:

function NearTile(playerid, tileid)
	if (neartile) then
		return true
	else
		return false
	end
end

Thanks in advance.

function checktiles(x, y, tileid)
	local results = {}

	x = x - 1
	y = y - 1
	for j = 0, 2 do
		for i = 0, 2 do
			local match = tile(x + i, y + j, "frame") == tileid
			results[j * 3 + i + 1] = match
		end
	end
	return results
end

This function will compare the tiles around the specified position and return the results as a table.

There are 9 tiles checked, a 3 by 3 area. The table indexes are mapped like this:

1 2 3
4 5 6
7 8 9

Where 5 is the index for the result at position X, Y.

If you want it to be more efficient you could unwrap the two loops

Thanks but someone already PM'd me a working function.

function NearTile(playerid, tileid)
	for x = player(playerid,"tilex") - 1, player(playerid,"tiley") + 1 do
		for y = player(playerid,"tiley") - 1, player(playerid,"tiley") + 1 do
			if ( x > -1 and y > -1 and tile(x, y, "frame") == tonumber(tileid) ) and ( x < map("sizex") and y < map("sizey") ) then
				return true
			end
		end
	end
	return false
end
