Write 99 multiplication table with two-dimensional array
$array = Array ();
for ($i =1; $i <=9; $i + +)
{
for ($j = 1; $j <= $i; $j + +)
{
$array [$j. '*' . $i] = $i * $J;
}
}
Echo '

';
Print_r ($array);

?>

where $array[$j. '*' . $i] = $i * $j, can this be replaced by a two-dimensional array output? Thank you.

$array [$j -1][$i-1] = $i * $j

 My four-floor code is the effect you want 
 1*1=1 
 1*2=2 2*2=4 
 
 1*3=3 2*3=6 3*3=9 
 
 1*4= 4 2*4=8 3*4=12 4*4=16 
 
 1*5=5 2*5=10 3*5=15 4*5=20 5*5=25 
 
 1*6=6 2*6=12 3*6=18 4*6=24 5*6=30 6*6=36 
 
 1*7= 7 2*7=14 3*7=21 4*7=28 5*7=35 6*7=42 7*7=49

1*8=8 2*8=16 3*8=24 4*8=32 5*8=40 6*8=48 7*8=56 8*8=64

1*9=9 2*9 =18 3*9=27 4*9=36 5*9=45 6*9=54 7*9=63 8*9=72 9*9=81
