    include_once('simple_html_dom.php');


    $url = "http://www.dsebd.org/news_archive_7days.php/";
    $ch = curl_init();
    $timeout = 5;
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, $timeout);
    $html = curl_exec($ch);
    curl_close($ch);
    $dom = new DOMDocument();
    @$dom->loadHTML($html);
    $tables = $dom->getElementsByTagName('tr');
    foreach($tables as $div) {

    if ($div->getElementsByTagName('td') ) {
        echo $div ->nodeValue;
    }
?>

Answer 1

看看这段代码（请注意，我添加了一条删除水平线以便于处理的行）：

// added this line
$html = str_replace('<tr>
    <td colspan="2" bgcolor="#DDDDDD"><span class="style1"><hr></span></td>
  </tr>', '', $html);

$dom = new DOMDocument();

@$dom->loadHTML($html);

$tables = $dom->getElementsByTagName('table');

$rows = $tables->item(0)->getElementsByTagName('tr');

$result = array();

$i = 0;
foreach ($rows as $row) {
    $i++;
    if($i < 4){
        continue;
    }
    $cols = $row->getElementsByTagName('td');
    $item = $cols->item(1);

    if($item){
        if($i % 4 === 0){
            $tmp = array();
            $tmp['trading_code'] = $item->nodeValue;
        }elseif($i % 4 === 1){
            $tmp['title'] = $item->nodeValue;
        }elseif($i % 4 === 2){
            $tmp['news'] = $item->nodeValue;
        }elseif($i % 4 === 3){
            $tmp['post_date'] = $item->nodeValue;
            $result[] = $tmp;
        }
    }
}
echo '<pre>';
print_r($result);
echo '</pre>';

输出是这样的：

Array
(
    [0] => Array
        (
            [trading_code] => SHY
            [title] => DSENEWS: Withdrawal of Authorized Representative

        )

    [3] => Array
        (
            [trading_code] => DUTCHBANGL
            [title] => DUTCHBANGL: Spot for AGM
            [news] => Trading of the shares of the Company will be allowed only in the Spot Market and Block transactions will also be settled as per spot settlement cycle with cum benefit from 13.03.2016 to 14.03.2016.

            [post_date] => 2016-03-10

    [4] => Array

            [post_date] => 2016-03-10
        )
// ... and goes on ...

这样您就可以访问特定值：

echo 'Trading code  : ' . $result[1]['trading_code'] . '<br>';
echo 'Title         : ' . $result[1]['title'] . '<br>';
echo 'News          : ' . $result[1]['news'] . '<br>';
echo 'Post Date     : ' . $result[1]['post_date'] . '<br>';

输出：

交易代码：EXCH
  标题：DSENEWS：每日营业额
  新闻：今天（10.03.2016）总交易额：95,239;成交量：111,966,997和营业额：Tk。 3,834.00万。
  发布日期：2016-03-10

您可以使用循环，创建表格等。使用您的想象力......

Answer 2

我使用过Simple HTML DOM Parser

可以是download from

include_once "simple_html_dom.php";
$html = file_get_html('http://www.dsebd.org/news_archive_7days.php/');
foreach($html->find('tr') as $element)
echo $element; '<br>';

在表中显示解析数据
