PHP for每个多维关联数组

Question

我有如下多维关联数组

  sr_array=>
    array (size=18)
  0 => string 'Shop' (length=4)
  1 => string 'Papu Kushwaha' (length=13)
  2 => string 'Jitendra Shukla' (length=15)
  3 => string 'Satish' (length=6)
  4 => string 'Pradeep' (length=7)
  5 => string 'Papu Khan' (length=9)
  6 => string 'Bharat' (length=6)
  7 => string 'Manoj Pandey' (length=12)
  8 => string 'select' (length=6)
  'Shop' => 
    array (size=9)
      'count_auto' => int 60
      'count_indus' => int 4
      'count_mc' => int 100
      'count_inverter' => int 10
      'count_in_bat' => int 40
      'total_credit' => int 191850
      'sale_value' => int 1351755
      'total_disc' => float 22377.38
      'perc_disc' => float 1.66

等....

现在我想以表格格式打印它们，我使用了以下代码输出

echo"<table border=1>";
            echo"<tr>";
            echo"<th></th>";

        for($i=0; $i < count($sr_array)/2; $i++){
            $current_sr = $sr_array[$i];
            echo"<th>{$current_sr}</th>";
        }
        echo"</tr>";
        $keys = array_keys($sr_array);
        for($i=0; $i < count($sr_array)/2; $i++){
            $current_sr = $sr_array[$i];
            echo"<tr>";
            echo"<td></td>";
            foreach($sr_array as $key => $var){
                 foreach($var as $x => $y)
                    echo"<td>{$y["count_auto"]}</td>";
             }
            echo"</tr>";
        }

请帮我下车

-------------------------------------
|           |Shop    |xyz      |abc   |
-------------------------------------
count_auto  |60      |75       | 85   |
-------------------------------------
count_indus | 25     | 74      |15    |
--------------------------------------
count_mc    |  55    | 212     | 15   |
-------------------------------------

等等

为foreach()提供无效参数

Thanks in advance

Answer 1

这里的基本问题是，当您在sr_array上迭代时，您假设这些值也是数组。这不是索引0到8的情况(据我所知)。这可以解释当前的问题。

理想情况下，数组的结构是一致的(理想情况下，是一个二维行数组，每个行包含一组字段)，然后一个简单的嵌套循环就可以工作了。

用for()/foreach()和循环迭代的组合来尝试下面的解

同样，考虑一个调换过的html表，其中数据作为列，描述作为行。否则需要复杂的迭代，因为数组项没有与html标记对齐。

echo "n<table>n";
$i = 0;
echo "n<tr>n";
echo "n<th></th>n";
foreach($sr_array as $item) {                 
    echo "<th>". array_keys($item)[$i] ."</th>n";
    $i++;
}
echo "</tr>n";
$j=0;
foreach($sr_array as $item) {
    echo "n<tr>n";
    echo "<td>" . array_keys($sr_array)[$j] . "</td>n";
            foreach($item as $key => $value)
            {
                echo "<td>". $value . "</td>n";
            }
    echo "</tr>n";
    $j++;
}
echo "n</table>n";

和输出如下(我重复你发布的数据为例):

               count_auto   count_indus count_mc count_inverter     count_in_bat total_credit sale_value total_disc perc_disc
