如何解析HTML表格到多維數組

Question

我試圖解析HTML表格到一個多維數組和存儲陣列到數據庫..

我的表的HTML看起來如下..

<div class="list"> 
     <table cellspacing="0"> 
     <tr class="tr-hover"> 
     <th rowspan="15" scope="row">Network</th> 
     <td class="ttl"><a href="network-bands.php3">Technology</a></td> 
     <td class="nfo"><a href="#" class="link-network-detail">GSM/HSPA/LTE</a></td> 
     </tr> 
     <tr class="tr-toggle"> 
     <td class="ttl"><a href="network-bands.php3">2G bands</a></td> 
     <td class="nfo">GSM 850/900/1800/1900 - SIM 1 & SIM 2 (optional)</td> 
     </tr><tr class="tr-toggle"> 
     <td class="ttl"><a href="network-bands.php3">3G bands</a></td> 
     <td class="nfo">HSDPA 850/900/1900/2100 </td> 
     </tr> 
     <tr class="tr-toggle"> 
     <td class="ttl"><a href="network-bands.php3">4G bands</a></td> 
     <td class="nfo"> LTE</td> 
     </tr> 
     <tr class="tr-toggle"> 
     <td class="ttl"><a href="glossary.php3?term=3g">Speed</a></td> 
     <td class="nfo">HSPA 42.2/5.76 Mbps, LTE Cat9 450/50 Mbps</td> 
     </tr> 

     <tr class="tr-toggle"> 
     <td class="ttl"><a href="glossary.php3?term=gprs">GPRS</a></td> 
     <td class="nfo">Yes</td> 
     </tr> 
     <tr class="tr-toggle"> 
     <td class="ttl"><a href="glossary.php3?term=edge">EDGE</a></td> 
     <td class="nfo">Yes</td> 
     </tr> 
     </table> 


     <table cellspacing="0"> 
     <tr> 
     <th rowspan="2" scope="row">Launch</th> 
     <td class="ttl"><a href=# onClick="helpW('h_year.htm');">Announced</a></td> 
     <td class="nfo">2016, February</td> 
     </tr> 
     <tr> 
     <td class="ttl"><a href=# onClick="helpW('h_status.htm');">Status</a></td> 
     <td class="nfo">Coming soon. 2016, March 11</td> 
     </tr> 
     </table> 


     <table cellspacing="0"> 
     <tr> 
     <th rowspan="6" scope="row">Body</th> 
     <td class="ttl"><a href=# onClick="helpW('h_dimens.htm');">Dimensions</a></td> 
     <td class="nfo">142.4 x 69.6 x 7.9 mm (5.61 x 2.74 x 0.31 in)</td> 
     </tr><tr> 
     <td class="ttl"><a href=# onClick="helpW('h_weight.htm');">Weight</a></td> 
     <td class="nfo">152 g (5.36 oz)</td> 
     </tr> 
     <tr> 
     <td class="ttl"><a href="glossary.php3?term=build">Build</a></td> 
     <td class="nfo">Corning Gorilla Glass back panel (unspecified version)</td> 
     </tr> 
     <tr> 
     <td class="ttl"><a href="glossary.php3?term=sim">SIM</a></td> 
     <td class="nfo">Single SIM (Nano-SIM) or Dual SIM (Nano-SIM, dual stand-by)</td> 
     </tr> 
     <tr><td class="ttl">&nbsp;</td><td class="nfo">- Samsung Pay (Visa, MasterCard certified)<br /> 
     - IP68 certified - dust proof and water resistant over 1.5 meter and 30 minutes</td></tr> 

     </table> 
</div> 

從這個

我想創建像

array (
      [Network] => 
      array (
       ['technology'] => 'GSM/HSPA/LTE', 
       ['2G bands'] => 'GSM 850/900/1800/1900 - SIM 1 & SIM 2 (optional)' 
       ... 
       ... 
       ... 
       so on 
      ), 

      ['Launch'] => 
      array (
       ['Announced'] => '2016, February', 
       .... 
       ... 
       so on 
      ), 

      ... 
      .. 
      ... 
      so on 

     ) 

我曾嘗試到現在是一個數組..

用於捲曲獲得HTML，然後使用DOM下面

  foreach ($e->find ('table') as $e1) { 
           $varinfo[] = $e1->innertext; 
          } 
          print_r($varinfo); 

視爲給定的，我得到

  Array ([0] => Network Technology GSM/HSPA/LTE 2G bands GSM 850/900/1800/1900 - SIM 1 & SIM 2 (optional) 3G bands HSDPA 850/900/1900/2100 4G bands LTE Speed HSPA 42.2/5.76 Mbps, LTE Cat9 450/50 Mbps GPRS Yes EDGE Yes [1] => Launch Announced 2016, February Status Coming soon. 2016, March 11 

所以有人可以幫助我得到多維array..i那種停留在這部分幾乎現在很長一段時間..

謝謝

Answer 1

$result = []; 

// get each table 
foreach ($html->find('table') as $t) { 
    // find the table header text to index the array 
    $idx = $t->find('th')[0]->plaintext; 
    // loop throught every td in the table 
    foreach ($t->find('td') as $td) { 
    if ($td->hasAttribute('class')) { 
     // if it's a title we use the text to index the array 
     if ($td->getAttribute('class') == 'ttl') { 
      $subIdx = $td->plaintext; 
      $result[$idx][$subIdx] = []; 
     } 
     // if it's information we put it into the array 
     else if ($td->getAttribute('class') == 'nfo'){ 
      $result[$idx][$subIdx] = $td->plaintext; 
     } 
    } 
    } 
} 

var_dump($result); 

[R ESULT：

array(3) { 'Network' => array(7) { 'Technology' => string(16) "GSM/HSPA/LTE" '2G bands' => string(54) "GSM 850/900/1800/1900 - SIM 1 & SIM 2 (optional)" '3G bands' => string(30) "HSDPA 850/900/1900/2100 " '4G bands' => string(4) " LTE" 'Speed' => string(41) "HSPA 42.2/5.76 Mbps, LTE Cat9 450/50 Mbps" 'GPRS' => string(3) "Yes" 'EDGE' => string(3) "Yes" } 'Launch' => array(2) { 'Announced' => string(14) "2016, February" 'Status' => string(27) "Coming soon. 2016, March 11" } 'Body' => array(5) { 'Dimensions' => string(45) "142.4 x 69.6 x 7.9 mm (5.61 x 2.74 x 0.31 in)" 'Weight' => string(15) "152 g (5.36 oz)" 'Build' => string(54) "Corning Gorilla Glass back panel (unspecified version)" 'SIM' => string(59) "Single SIM (Nano-SIM) or Dual SIM (Nano-SIM, dual stand-by)" ' ' => string(132) "- Samsung Pay (Visa, MasterCard certified) - IP68 certified - dust proof and water resistant over 1.5 meter and 30 minutes" } }
