Question

用于填充表所需的循环。但我继续得到额外的两列，重复前两列中的数据。我的for循环出了什么问题？感谢所有帮助。

                            echo "<td>" . $i . "</td>"; 
                            echo "<td>" . ($p = number_format(($p * pow((1 + $r), $i)), 2)) . "</td>";
                            $n++;

你有$j的循环，不需要！所以使用这个：

<?php  
    for($i = 1; $i <= 10; $i++) { 
        echo "<tr>";  
        $p = 1000;
        $r = 0.05;
        $n = 1;

        echo "<td>" . $i . "</td>"; 
        echo "<td>" . ($p = number_format(($p * pow((1 + $r), $i)), 2)) . "</td>";
        $n++;
        echo "</tr>";  
    }  
?>

使用PHP for循环填充html表
