これも何に使うんですかと言われるでしょうが(;^_^A。

<?php
for($i=1;$i<=9;$i++){
    for($j=1;$j<=9;$j++){
        if($j!=9){
            echo $j*$i." ";
        }else{
            echo $j*$i."\n";
        }
    }
}
?>

外側ループの$iと、内側ループの$jをかけて行き、その行の最後の数字だけに改行コードを付けることで完成します。、

結果

1 2 3 4 5 6 7 8 9
2 4 6 8 10 12 14 16 18
3 6 9 12 15 18 21 24 27
4 8 12 16 20 24 28 32 36
5 10 15 20 25 30 35 40 45
6 12 18 24 30 36 42 48 54
7 14 21 28 35 42 49 56 63
8 16 24 32 40 48 56 64 72
9 18 27 36 45 54 63 72 81
