[Help] Numbering PHP table

[fromar123]

Hi,
i am trying to make a table using PHP, and i have a problem numbering each cell with a different number. So if the table is 3x3, like this
1 2 3
4 5 6
7 8 9

Here is what i got (i know what is worng, i am displaying td numbers, but i dont know how to do it like i want...) :

<?php 

function drawTable(){

$rows = 4; // amout of tr
$cols = 4;// amjount of td

echo "<table border='1'>"; 


for($tr=1;$tr<=$rows;$tr++){ 

echo "<tr>";
for($td=1;$td<=$cols;$td++){
	echo "<td align='center'>".$td."</td>";
}

echo "</tr>";
}

echo "</table>";
}

drawTable();
?>

You could keep another variable that just increases by 1 every time you print a cell. Or look at your own illustration

1 2 3
4 5 6
7 8 9

and use the fact that it shows how with a trivial bit of maths you can calculate the number for a cell given its row and column: [font=monospace]($tr - 1) * 3 + $td[/font].
