PHPを使用してこのhtmlテーブルをcsvで自動的に変換する必要があります。誰かがこれを行う方法について何かアイデアを提供できますか？ありがとう。

$table = '<table border="1">
<tr>
<th>Header 1</th>
<th>Header 2</th>
</tr>
<tr>
<td>row 1, cell 1</td>
<td>row 1, cell 2</td>
</tr>
<tr>
<td>row 2, cell 1</td>
<td>row 2, cell 2</td>
</tr>
</table>';

みんな、私は.csvファイルだけに変換するために$ tableが必要です。これは、いくつかのPHP関数を使用して自動的に生成できます。そのcsvファイルのパスを/test/ home/path_to_csvに定義できます

http://simplehtmldom.sourceforge.net/を使用できますstr_get_html 

include "simple_html_dom.php";
$table = '<table border="1">
<tr>
<th>Header 1</th>
<th>Header 2</th>
</tr>
<tr>
<td>row 1, cell 1</td>
<td>row 1, cell 2</td>
</tr>
<tr>
<td>row 2, cell 1</td>
<td>row 2, cell 2</td>
</tr>
</table>';

$html = str_get_html($table);



header('Content-type: application/ms-excel');
header('Content-Disposition: attachment; filename=sample.csv');

$fp = fopen("php://output", "w");

foreach($html->find('tr') as $element)
{
        $th = array();
        foreach( $element->find('th') as $row)  
        {
            $th [] = $row->plaintext;
        }

        $td = array();
        foreach( $element->find('td') as $row)  
        {
            $td [] = $row->plaintext;
        }
        !empty($th) ? fputcsv($fp, $th) : fputcsv($fp, $td);
}


fclose($fp);

誰かが Baba の答えを使用しているが、余分な空白が追加されていることに頭を悩ませている場合、これは機能します。

include "simple_html_dom.php";
$table = '<table border="1">
<tr>
<th>Header 1</th>
<th>Header 2</th>
</tr>
<tr>
<td>row 1, cell 1</td>
<td>row 1, cell 2</td>
</tr>
<tr>
<td>row 2, cell 1</td>
<td>row 2, cell 2</td>
</tr>
</table>';

$html = str_get_html($table);   

$fileName="export.csv";
header('Content-type: application/ms-excel');
header("Content-Disposition: attachment; filename=$fileName");

$fp = fopen("php://output", "w");
$csvString="";

$html = str_get_html(trim($table));
foreach($html->find('tr') as $element)
{

    $td = array();
    foreach( $element->find('th') as $row)
    {
        $row->plaintext="\"$row->plaintext\"";
        $td [] = $row->plaintext;
    }
    $td=array_filter($td);
    $csvString.=implode(",", $td);

    $td = array();
    foreach( $element->find('td') as $row)
    {
        $row->plaintext="\"$row->plaintext\"";
        $td [] = $row->plaintext;
    }
    $td=array_filter($td);
    $csvString.=implode(",", $td)."\n";
}
echo $csvString;
fclose($fp);
exit;

}

このスレッドで見つかったコードに基づいて単純なクラスを適応させ、現在は と を処理colspanしていrowspanます。十分にテストされておらず、最適化できると確信しています。

使用法：

require_once('table2csv.php');

$table = '<table border="1">
    <tr>
    <th colspan=2>Header 1</th>
    </tr>
    <tr>
    <td>row 1, cell 1</td>
    <td>row 1, cell 2</td>
    </tr>
    <tr>
    <td>row 2, cell 1</td>
    <td>row 2, cell 2</td>
    </tr>
    <tr>
    <td rowspan=2>top left row</td>
    <td>top right row</td>
    </tr>
    <tr>
    <td>bottom right</td>
    </tr>
    </table>';

table2csv($table,"sample.csv",true);
