99乘法表(PHP版)

本文主要是介绍99乘法表(PHP版)，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

代码：

for ($i = 1; $i <= 9; $i++){for ($j = 1; $j <= 9; $j++){if ($i >= $j){printf("%2d * %2d = %2d   ", $j , $i, $i * $j);}}echo "\n";
}

运行结果：

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
