    $data = "$i and $j<br>";

Try with:

$data = '';
for($i=0,$j=0; $i<=10, $j<=10; $i++,$j++){
    $data .= "$i and $j<br/>";
}
echo $data;

is it really the loop you want ? 1 1, 2 2, 3 3 ? to have 1 1, 1 2, 1 3, ... do:

$data = '';
for($i=0; $i<=10; $i++){
    for($j=0; $j<=10; $j++){
        $data .= "$i and $j<br/>";
    }
}
echo $data;
