PHPQuery-選擇表列到一個數組

Question

我有一個HTML文件，像這樣的表：

<tr valign="top" class="dselbkg" onMouseOver="this.className='selbkg'" onMouseOut="this.className='dselbkg'" > 
    <td height="20" align="center">1</td> 
    <td height="20"><div align="center">16-12-2014</div></td> 
    <td ><div align="center">1ST<br> 
      (10:0 AM - 1:0 PM)</div></td> 
    <td ><div align="center">BE2105 </div></td> 
    <td >PROGRAMMING IN C</td> 
</tr> 

<tr valign="top" class="dselbkg" onMouseOver="this.className='selbkg'" onMouseOut="this.className='dselbkg'" > 
    <td height="20" align="center">2</td> 
    <td height="20"><div align="center">18-12-2014</div></td> 
    <td ><div align="center">1ST<br> 
      (10:0 AM - 1:0 PM)</div></td> 
    <td ><div align="center">BS1101 </div></td> 
    <td >MATHEMATICS - I</td> 
</tr> 

<tr valign="top" class="dselbkg" onMouseOver="this.className='selbkg'" onMouseOut="this.className='dselbkg'" > 
    <td height="20" align="center">3</td> 
    <td height="20"><div align="center">20-12-2014</div></td> 
    <td ><div align="center">1ST<br> 
      (10:0 AM - 1:0 PM)</div></td> 
    <td ><div align="center">HM3101 </div></td> 
    <td >COMMUNICATIVE ENGLISH</td> 
</tr> 

我需要每個<td>進入基於類ID陣列的獨立元件。

我正在使用PHPQuery。我試過

$table = $all['tr.dselbkg']; 
$columns = $table['td']; 

但是它所做的是將所有的列作爲單個字符串。所以$columns[0]打印出所有的列，而$columns[1]是空白的。

如何將個人<td>作爲數組中的單個元素使用？

編輯使用PHPQuery：

<?php 

include('phpQuery.php'); 

$htmlString = '<tr valign="top" class="dselbkg" onMouseOver="this.className=\'selbkg\'" onMouseOut="this.className=\'dselbkg\'" > 
    <td height="20" align="center">1</td> 
    <td height="20"><div align="center">16-12-2014</div></td> 
    <td ><div align="center">1ST<br> 
      (10:0 AM - 1:0 PM)</div></td> 
    <td ><div align="center">BE2105 </div></td> 
    <td >PROGRAMMING IN C</td> 
</tr> 

<tr valign="top" class="dselbkg" onMouseOver="this.className=\'selbkg\'" onMouseOut="this.className=\'dselbkg\'" > 
    <td height="20" align="center">2</td> 
    <td height="20"><div align="center">18-12-2014</div></td> 
    <td ><div align="center">1ST<br> 
      (10:0 AM - 1:0 PM)</div></td> 
    <td ><div align="center">BS1101 </div></td> 
    <td >MATHEMATICS - I</td> 
</tr> 

<tr valign="top" class="dselbkg" onMouseOver="this.className=\'selbkg\'" onMouseOut="this.className=\'dselbkg\'" > 
    <td height="20" align="center">3</td> 
    <td height="20"><div align="center">20-12-2014</div></td> 
    <td ><div align="center">1ST<br> 
      (10:0 AM - 1:0 PM)</div></td> 
    <td ><div align="center">HM3101 </div></td> 
    <td >COMMUNICATIVE ENGLISH</td> 
</tr> '; 

$doc = phpQuery::newDocumentHTML($htmlString); 

foreach (pq('tr.dselbkg') as $row){ 
    $columns = array(); 
    foreach(pq('td',$row) as $td) $columns[] = $td->nodeValue; 
    $tableRows[] = $columns; 
} 

print_r($tableRows); 

/* 
Array 
(
    [0] => Array 
     (
      [0] => 1 
      [1] => 16-12-2014 
      [2] => 1ST 
      (10:0 AM - 1:0 PM) 
      [3] => BE2105 
      [4] => PROGRAMMING IN C 
     ) 

    [1] => Array 
     (
      [0] => 2 
      [1] => 18-12-2014 
      [2] => 1ST 
      (10:0 AM - 1:0 PM) 
      [3] => BS1101 
      [4] => MATHEMATICS - I 
     ) 

    [2] => Array 
     (
      [0] => 3 
      [1] => 20-12-2014 
      [2] => 1ST 
      (10:0 AM - 1:0 PM) 
      [3] => HM3101 
      [4] => COMMUNICATIVE ENGLISH 
     ) 

)

您可以輕鬆地使用simple html dom來查詢您的HTML。

下面是如何從解析的td元素構建數組的示例。

<?php 

include('simple_html_dom.php'); 

$htmlString = '<tr valign="top" class="dselbkg" onMouseOver="this.className=\'selbkg\'" onMouseOut="this.className=\'dselbkg\'" > 
    <td height="20" align="center">1</td> 
    <td height="20"><div align="center">16-12-2014</div></td> 
    <td ><div align="center">1ST<br> 
      (10:0 AM - 1:0 PM)</div></td> 
    <td ><div align="center">BE2105 </div></td> 
    <td >PROGRAMMING IN C</td> 
</tr> 

<tr valign="top" class="dselbkg" onMouseOver="this.className=\'selbkg\'" onMouseOut="this.className=\'dselbkg\'" > 
    <td height="20" align="center">2</td> 
    <td height="20"><div align="center">18-12-2014</div></td> 
    <td ><div align="center">1ST<br> 
      (10:0 AM - 1:0 PM)</div></td> 
    <td ><div align="center">BS1101 </div></td> 
    <td >MATHEMATICS - I</td> 
</tr> 

<tr valign="top" class="dselbkg" onMouseOver="this.className=\'selbkg\'" onMouseOut="this.className=\'dselbkg\'" > 
    <td height="20" align="center">3</td> 
    <td height="20"><div align="center">20-12-2014</div></td> 
    <td ><div align="center">1ST<br> 
      (10:0 AM - 1:0 PM)</div></td> 
    <td ><div align="center">HM3101 </div></td> 
    <td >COMMUNICATIVE ENGLISH</td> 
</tr> '; 

$html = str_get_html($htmlString); 

foreach($html->find('tr.dselbkg') as $tr){ 
    $columns = array(); 

    foreach($tr->find('td') as $td) 
     $columns[] = $td->outertext; // outertext if you want the full td tag 
     // $columns[] = $td->innertext // innertext if you just want the text inside the td tag 

    $tablerows[]=$columns; 
} 

print_r($tablerows); 

/*
