Undefined offset: 5 in [file location] on line 22

Arrays are indexed starting with 0. Consequently, your array initialization has populated indexes 0 through 4:

Code:

$table = array ("1", "2", "3", "4", "5");

is equivalent to

Code:

$table[0]="1";
$table[1]="2";
$table[2]="3";
$table[3]="4";
$table[4]="5";

Except you're trying to access index number 5, which does not exist:

Code:

$rows = 6;
for($z = 0; $z < $rows; $z++)
    if ($table[$i + $z] !=0)
      (snip)

That loop will be executed for $z values 0 through 5, and that's assuming $i remains 0.

There isn't a nice way of telling you that, but the code you posted doesn't make sense in some parts. What exactly are you trying to achieve with it? What is $taulukko supposed to be?

oops, forgot to translate that $table over there.
What I'm trying to achieve is to create a table that creates each row with the same text and calling it the row it is.

EDIT: Managed to solve it somehow :_D

If that's all you need, a single for loop will be sufficient:

Code:

<!DOCTYPE html>
<html>
	<head>
		<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
		<title></title>
	</head>
	<body>
		<table border='1'>
		<?php
		$rows = 6;
		for($i=0; $i < $rows; $i++)
			echo "<tr><td>This is row {$i + 1}</td></tr>";
		?>
		</table>
	</body>
</html>
