我想创建一个 10*10 的表，并用一个 1-100 范围内的数组填充它。每次我尝试回显值时，它都会回显每个单元格中数组的最后一个值。

有人可以查看我的代码并告诉我我做错了什么吗？
打印出来的是：
100 100 100 100 100.....100
100 100 100 100 100.....100

我想要的是什么？
1 2 3 4 5......10
11 12 13 14......20

<?php
function Chart($width, $height, $fill) {
   $cell= range(0,100,1);
   $key=0;
foreach ($cell AS $key => $value) {echo $value;}
print_r ($cell);
$chart = '<table border="0" cellpadding="5">';
    for ($i = 0; $i < $height; $i++) {
    $chart .= "<tr>";
    for ($j = 0; $j < $width; $j++) {
        $chart .= "<td>$value</td>";
    }
    $chart .= "</tr>";
    }
return $chart.="</table>";}
?>
<html>
  <body>
    <?php echo Chart(10, 10, $value); ?>
  </body>
</html>

试试这个：

<?php
        $width = 10;
        $height = 10;
        $cell = 0;

        $data = '<table>';

        for ($i = 0; $i < $width; $i++) {
            $data.= '<tr>';
            for ($j = 1; $j <= $height; $j++) {
                $data.='<td>'.++$cell.'</td>';
            }
            $data.= '</tr>';
        }
        $data.= '</table>';

        echo $data;
        ?>

- 谢谢

    // not 100% sure what you intended to do with $fill
    // if the $width is 10 & the $height is 10, there will be 100 <td>s (10*10)
    function chart($width, $height) 
    {
        // set the $chart to be "" initially to append values later
        $chart = "";

        $cells = 0;

        // keep looping until $h is not less than $height [example] 10x
        for ($h = 0; $h < $height; $h++)

                // this is pre-incrementing because it starts at 0, but you need it to start at 1 and to make it get to 100
                $chart .= "\t\t<td>".++$cells."</td>\n";
            }
            $chart .= "\t</tr>\n";
        }   

        // return the table with all the content inside of it
        return "<table border=\"0\" cellpadding=\"5\">\n".$chart.'</table>';
    }


?><!DOCTYPE html> <!-- HTML5, this is on the first line after the php end block to prevent a space before the Doctype and thus quirks mode in earlier versions of IE -->
    <?php echo chart(10, 10); // or you can use the php shorttag like <?= Chart(10, 10); ? > ?>
