php - How to get the specific <td> while scraping a web page table using a DOM? -

i've table, of number of columns can change depending on configuration of scrapped page (i have no control of it). want information specific column, designated columns heading.

sample table:

<table>     <tr>         <td>name</td>         <td>age</td>         <td>marks</td>     </tr>     <tr>         <td>a</td>         <td>20</td>         <td>90</td>     </tr>     <tr>         <td>b</td>         <td>21</td>         <td>80</td>     </tr>     <tr>         <td>c</td>         <td>22</td>         <td>70</td>     </tr> </table> 

my working php code display columns:

foreach($html->find("table#table2 tr td") $td) {   $code = $td;   echo $code; } 

needed code format:

foreach($html->find('table#table2 td') $td) {   /* td1 data */    /* code1 store td data 1 */    /* next td data */    /* code2 store td data 2 */    /* next td data */    /* code3 store td data 3 */ } 

i want extract output , store db table having table name result in appropriate columns.

i can write storing code myself. need code retrieve consecutive td data inside row without loop.since code store td data varies.

posts referred - scraping webpage.

// create dom url or file $html = file_get_html("http://www.example.org/");  // find tr array $tr_array = $html->find("table#table2 tr");  $td_array = []; // find td array foreach($tr_array $tr) {     array_push($td_array,$tr->find("td")); }  echo "<table id=\"table1\">"; foreach($tr_array $tr) {     echo "<tr>";     foreach($td_array $td) {         echo $td;     }     echo "</tr>"; } echo "</table>";

in above code, i've stored array objects inside arrays:

<?php  $a = []; $a1 = [1,2,3]; $a2 = [4,5,6]; array_push($a,$a1,$a2); foreach($a $a_e) {   foreach($a_e $e) {     echo $e;   }   echo "<br>"; }  ?> 

outputs:

123
