如何使用PHP MySQL创建矩阵动态

Question

任何人都可以帮助我吗？我发现使用PHP编程创建矩阵动态很困难。我想从mysql数据库中获得矩阵动态值。

例如：

INF 56  78  67
45  INF 78  67
45  56  INF 67
45  56  78  INF

这段代码：

function    random()
{
    $max = 7;
    if (isset($_POST['amount']))
    {
        $amount = (int)$_POST['amount'];
        $rows = ($amount > 2 && $amount < 15) ? $amount : 3;
    }
    else
    {
        $rows = rand(3, 7);
    }
    for ($i = 1; $i <= $rows; $i++)
    {
        for ($j = 1; $j <= $rows; $j++)
        {
            $this->table[$i][$j] = $i == $j ? INF : rand(0, 99);
        }
    }
}


function    __toString()
{
    $str = '<table class="table table-bordered" id="tableInput"><tbody>';
    $str .= '<tr><td></td>';
    foreach ($this->table as $rowName => $row)
    {
        $str .= "<td>$rowName</td>";
    }
    $str .= '</tr>';
    foreach ($this->table as $rowName => $row)
    {
        $str .= "<tr><td>$rowName</td>";
        foreach ($row as $columnName => $value)
        {
            $str .= "<td>";
            $str .=
                '<input class="form-control" type="text" value="' . $value . '" name="table[' . $rowName . '][' .
                $columnName . ']" requied' . ($columnName == $rowName ? ' disabled' : '') . '>';
            $str .= "</td>";
        }
        $str .= '</tr>';
    }
    $str .= '</tbody></table>';
    return $str;
}
