Accessing html tables in PHP

Question

I have a question regarding the access of html elements.

File1.PHP

<table id="tableID">
<tr>
    <td>&nbsp
    </td>
</tr>
</table>
<input type=button onclick=changeValue();>
<script type="text/javascript" src="file2.JS"></script>

File2.JS

function changeValue(){ 
//HAS AJAX OBJECT THAT CALLS file3.php to read a file
ajax.doPost("file3.php", callback); }

File3.php

  function fileRead(){
   ...
   $line = fgets($file_handle);
   ///After reading the lines of the file in File3.php 
   ///I want to output it in the table in File1.PHP without returning 
   ///it as xmlResponse to File2.JS
   ///Is it possible to acces the table in File1.PHP here?
 }

Is this flow possible? Because I can't make it work.

Help..

It'll be much easier if you just pass all the necessary values from file1.php with AJAX to file3.php — Fad

@KemalFadillah you mean i would get the table object from file2.js and pass it also to file3.php? — tinks

Actually, I was thinking of traversing the DOM with JavaScript and grab all the values you need from the table and then send them through AJAX. I'm pretty sure what you're looking for is the data and not the table itself. — Fad

@KemalFadillah its the read values to the table.. i used ajax and thought of returning the read values through xmlResponse but file is quite big.. so i wanted to directly access the table to populate. — tinks

The easiest way to get a similiar behavior is to put the table into its own file

table.php

<?php
  ob_start();
?>
<table id="tableID">
  <tr>
    <td>&nbsp</td>
  </tr>
</table>
<?php
  // Save content of this page in a variable
  $table = ob_get_contents();
  ob_end_clean();
?>

File1.PHP

<?php
  include "table.php";
  // Access $table defined in table.php
  echo $table;
?>
<input type=button onclick=changeValue();>
<script type="text/javascript" src="file2.JS"></script>

File3.php

  function fileRead(){
   // Access $table defined in table.php
   echo $table;
 }

yes it is possible.

function changeValue(){ 
$.ajax({
                type: "POST",
                data:"filenametoread=filename",
                url:"path to file3.php
                success: function(msg){
                   $("#tableID").html(msg);  
                }
            });
}

file3.php

if(isset($_REQUEST['filenametoread']){
      return fileRead($_REQUEST['filenametoread']);
}
function fileRead($filename){
   ...
   $line = fgets($file_handle);
   return $line;
 }

I don't think so you can access file1.php content here!(if not passed as an ajax data)
