php 打印乘法口绝表代码

PHP是老师经常会要我们做这个的题目,今天我再做一次打印乘法口决,PHP代码如下:

";
echo "

"; for ($i = 1; $i "; for ($j = 1; $j " . $j . "*" . $i . "=" . ($j * $i) . ""; } echo ""; } echo ""; echo "





"; echo ""; for ($i = 1; $i "; for ($j = $i; $j " . $i . "*" . $j . "=" . ($j * $i) . ""; } echo ""; } echo ""; ?>

一个简单的求和

 1) {
        return sum($n - 1) + $n;
    } else {
        return 1;
    }
}
echo sum(100);
?>
