PHP输出乘法口诀，用while循环实现

Sure, here's an example PHP code to output the multiplication table using a while loop:

$num = 1;
while ($num <= 9) {
$i = 1;
while ($i <= $num) {
echo "$i x $num = " . ($i * $num) . " ";
$i++;
}
echo "<br>";
$num++;
}

This will output the multiplication table from 1x1 up to 9x9.

乘法口诀表while循环

i = 1
while i <= 9:
    j = 1
    while j <= i:
        print(f"{j}*{i}={i*j}", end="\t")
        j += 1
    print()
    i += 1

输出结果：

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	

Python语言 用while循环输出九九乘法口诀表

可以使用两个嵌套的 while 循环来实现九九乘法口诀表的输出。代码如下：

i = 1
while i <= 9:
    j = 1
    while j <= i:
        print(j, "*", i, "=", i * j, end="\t")
        j += 1
    print("\n")
    i += 1

运行结果如下：

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
