基于键中字符的PHP分离数组

我有一个来自提交表单的PHP数组，如下所示

$form_data = Array (
    [input_1_1] => Product Name
    [input_1_2] => $8.00
    [input_1_3] => 2
    [input_2_1] => Other Product Name
    [input_2_2] => $3.50
    [input_2_3] => 8
)

我正在寻找解析此内容的最佳方法，以便构建如下标记：

<table>
    <tr>
        <td>Product Name</td>
        <td>$8.00</td>
        <td>2</td>
    </tr>
    <tr>
        <td>Other Product Name</td>
        <td>$3.50</td>
        <td>8</td>
    </tr>
</table>

品名
$8.00
2.
其他产品名称
$3.50
8.

做这件事最合乎犹太教的方式是什么

我是否应该根据第一个数字将此数组拆分为更小的数组（然后循环）？ 或者，我应该基于三个集合构建标记，如：

<table>
    <tr>
        <td><?php echo $form_data[1]; ?></td>
        <td><?php echo $form_data[2]; ?></td>
        <td><?php echo $form_data[3]; ?></td>
    </tr>
    <tr>
        <td><?php echo $form_data[4]; ?></td>
        <td><?php echo $form_data[5]; ?></td>
        <td><?php echo $form_data[6]; ?></td>
    </tr>
</table>

非常感谢您的帮助/建议。

看看这个例子：

预期的HTML格式：

foreach( $chunk as $val ){
    echo "<tr>";
    foreach($val as $v){
        echo "<td>" . $v . "</td>";
     }
    echo "</tr>";
}

foreach（$chunk作为$val）{
回声“；
外币（$val为$v）{
回声“$v.”；
}
回声“；
}

试试这个

$form_data = Array (
'[input_1_1]' => 'Product Name',
'[input_1_2]' => '$8.00',
'[input_1_3]' => '2',
'[input_2_1]' => 'Other Product Name',
'[input_2_2]' => '$3.50',
'[input_2_3]' => '8'
);

echo "<table>";
foreach($form_data as $k=>$v)
{
echo "<tr>";
echo "<td>".$v."&lt/td>";
echo "</tr>";
}
echo "</table>";

假设每个表行各有3个元素

<?php

echo "<table>
        <tr>";

$form_data = Array (
    "input_1_1" => "Product Name",
    "input_1_2" => "$8.00",
    "input_1_3" => "2",
    "input_2_1" => "Other Product Name",
    "input_2_2" => "$3.50",
    "input_2_3" => "8"
);

$intRowBefore = 1;
foreach( $form_data as $strKey => $strVal ) {

   $intRow = explode("_", $strKey)[1];

   if( $intRowBefore != $intRow ) {
      echo "</tr><tr>";
      $intRowBefore = $intRow;
   }

   echo "<td>". $strVal ."</td>";


}

echo "</tr></table>";

考虑

<?php
$form_data = array();
$form_data['input_1_1'] = 'Product Name';
$form_data['input_1_2'] = '$8.00';
$form_data['input_1_3'] = '2';
$form_data['input_2_1'] = 'Other Product Name';
$form_data['input_2_2'] = '$3.50';
$form_data['input_2_3'] = '8';

// Get unique keys
function get_unique_keys($keys)
{
    $arr = array();
    foreach($keys as $k=>$v){
        $arr[] = substr($k, 0, strlen($k)-2);
    }
    return array_unique($arr);
}

$keys = get_unique_keys($form_data);

// Output
printf("<table>\n");
foreach($keys as $k)
{
    printf("  <tr>\n");
    printf("    <td>%s</td>\n", $form_data[$k.'_1']);
    printf("    <td>%s</td>\n", $form_data[$k.'_2']);
    printf("    <td>%s</td>\n", $form_data[$k.'_2']);
    printf("  </td>\n");
}
printf("</table>\n");


是否有可能修改表单以使用数组样式名称？可能-请提供一个数组样式名称的示例？另一个XY问题：这不是预期的输出。它用新行打印每个值。只需将<替换为>并将其固定，谢谢。你们这些PHP开发者是一群很有帮助的人！
foreach ($_POST['name'] AS $i => $name) {
    $price = $_POST['price'][$i];
    $quantity = $_POST['quantity'][$i];
    // Output the table row
}

$form_data = Array (
'[input_1_1]' => 'Product Name',
'[input_1_2]' => '$8.00',
'[input_1_3]' => '2',

'[input_2_2]' => '$3.50',
'[input_2_3]' => '8'
);

echo "&lt;table&gt;";
foreach($form_data as $k=>$v)
