如何将指定PHP数组转换为符合自定义格式的HTML表格？

First, let's fix the core issue with your original code: it was treating each subarray as a column instead of a row, which is why all data ended up in two rows. Here's the corrected approach that meets your requirements:

Step-by-Step Explanation #

1. Define the Size Headers: We explicitly list the required size values (34, 35, 38, 39, 40, 41) since they're fixed per your request.
2. Build the Header Row: Start with "Loc" followed by each size as table headers.
3. Loop Through Each Data Entry: For every subarray in your main array, create a table row that displays the Loc value once, followed by the corresponding size values (ignoring the [0] element entirely).

Corrected PHP Code #

<?php
// Your original array
$result = [
    ['Loc' => 124, 0 => 124, 34 => 1, 35 => 1, 38 => 2, 39 => 2, 40 => 1, 41 => 1],
    ['Loc' => 424, 0 => 424, 34 => 1, 35 => 1, 38 => 0, 39 => 0, 40 => 0, 41 => 0],
    ['Loc' => 1512, 0 => 1512, 34 => 1, 35 => 1, 38 => 0, 39 => 0, 40 => 0, 41 => 0],
    ['Loc' => 1612, 0 => 1612, 34 => 0, 35 => 0, 38 => 1, 39 => 1, 40 => 2, 41 => 2],
    ['Loc' => 1711, 0 => 1711, 34 => 0, 35 => 0, 38 => 1, 39 => 1, 40 => 1, 41 => 1]
];

// Define the size columns we need
$sizes = [34, 35, 38, 39, 40, 41];

// Start the table
echo '<table border="1">';

// Header row
echo '<tr>';
echo '<th>Loc</th>';
foreach ($sizes as $size) {
    echo "<th>$size</th>";
}
echo '</tr>';

// Data rows
foreach ($result as $item) {
    echo '<tr>';
    // Display Loc once per row
    echo "<td>{$item['Loc']}</td>";
    // Display each size value
    foreach ($sizes as $size) {
        echo "<td>{$item[$size]}</td>";
    }
    echo '</tr>';
}

// End the table
echo '</table>';
?>

Resulting HTML Table #

When rendered, this code will produce a table matching your expected output:

This solution ensures:

• Loc is shown once per row
• The [0] element is completely ignored
• Only the required size columns (34-41) are displayed as headers and data
