Question

2个不同长度的数组

$status = array(
          array("up","down","down","up"),
          array("down","up","up","down"));

$room = array("RM101", "RM102","RM103","RM104","RM105", "RM106","RM107","RM108");

我们如何才能有2列，Top标题为$room数组，行为$status。

表格应如下所示：

This is how the table should look like

请帮我解决这个问题，我是PHP编程的新手。

请参阅下面我尝试过的编码。

 <?PHP
function room(){
    $n = 0;
    $rooms = array("RM101","RM102","RM103","RM104","RM105","RM106","RM107","RM108");
    {
        if ($n % 24 == 0) { 
        echo '<tr><td>'.$rooms[$m].'</td>';   
        }
        else 
        {
        echo '<td>'.$rooms[$m].'</td>'; 
        }
        $n++;
    }
}

function status(){
    $c=0;
    $nodes = array('http://x.x.xx.xx/rpFirstPageStatistics.html','http://x.x.xx.xx/rpFirstPageStatistics.html');
    $node_count = count($nodes);

    $curl_arr = array();
    $master = curl_multi_init();

    for($i = 0; $i < $node_count; $i++)
    {
    $Username = "xxx";
    $Password = "xxx";

        $url =$nodes[$i];
        $curl_arr[$i] = curl_init($url);
        curl_setopt($curl_arr[$i], CURLOPT_RETURNTRANSFER, true);
        curl_setopt($curl_arr[$i], CURLOPT_USERPWD, "$Username:$Password");  
        curl_multi_add_handle($master, $curl_arr[$i]);

    }

    do {
        curl_multi_exec($master,$running);
    } while($running > 0);

    for($i = 0; $i < $node_count; $i++)
    {
        $results = curl_multi_getcontent  ( $curl_arr[$i]  );
        preg_match_all('~<\/td><TD  width="65">(.*?)<\/td>~s', $results, $status); 
        foreach ($status as $value => $values){
        }
        foreach (array_slice($values,2) as $x=>$x_value){
            if ($c % 24 == 0) {
                echo '<tr><td>'.$x_value.'</td>';  
            }else {
                echo '<td>'.$x_value.'</td>'; 
            }
            $c++;
        }
    }
}
?>

Answer 1

array functions可以帮助您完成所有这些工作。

您可以使用array_merge(...$status)将$status中的子数组合并到一个包含8个项目的数组中。如果您的PHP太旧而无法使用...运算符，则可以使用call_user_func_array("array_merge", $status)。

假设$status数组总共包含与$room数组相同数量的项目，则可以将它们组合成一个列表，其中房间为键，状态为array_combine的值。然后你有一个像这样的数组：

["RM101" => "up", "RM102" => "down", "RM103" => "down", ...]

要将其拆分为包含两列的行，请使用array_chunk并将$preserve_keys标记设置为true。

[["RM101" => "up", "RM102" => "down"], ["RM103" => "down", ...], ...]

现在数组大致处于您想要的结构中，它只是循环遍历行并输出HTML的情况。在每个块中，我们可以使用array_keys获取一对房间名称，array_values（这不是绝对必要的）来获取这对状态，并implode加入数组一起变成一个字符串。

把它们放在一起你得到

$status = array(
          array("up","down","down","up"),
          array("down","up","up","down"));

$room = array("RM101", "RM102","RM103","RM104","RM105", "RM106","RM107","RM108");

echo "<table>";
foreach (array_chunk(array_combine($room, array_merge(...$status)), 2, true)
         as $block) {
    echo "<tr><th>" . implode("</th><th>", array_keys($row)) . "</th></tr>";
    echo "<tr><td>" . implode("</td><td>", array_values($row)) . "</td></tr>";
}
echo "</table>";

Answer 2

请尝试以下格式：

<强> HTML：

<table>
<thead>
    <tr>
        <th>Product</th>
        <th>Width</th>
        <th>Material</th>
    </tr>
</thead>
<tbody>
    <tr>
        <th><img /></th>
        <td>50mm</td>
        <td>Plastic</td>
    </tr>
</tbody>
</table>

<强> PHP：

foreach ($rows as $row) {
$similar_com .= "<tr>";
$similar_com .= "<td><img style='width: 100px; height: 100px;' src='$row->image_url' alt='$row->model_no' /><br />$row->name</td>";
$similar_com .= "<td>$row->width mm</td>";
...
}
