using php to fill in an existing table
<p>I have a blank html table (column) on my page. I have a csv file with last years info for 
that column available, but I don't want to initially write those values into the table 
cells (because there might be new info which needs to be manually entered). I would like 
to make a button which would populate this column. What would be the best way of going 
about this? Since I want the info entered dynamically I would obviously need to use an 
ajax call, and I would call a php file because that has a useful function fgetcsv(), but 
can I use this function to enter info into a existing table?  I was able to use php to 
CREATE a table with this info, but as far as I understand, php has no knowledge of the 
DOM... I would have to somehow package the entire column info and have javascript do the 
job but I'm a little confused as to how...</p>

<p>Below is a snippet of how I used php to CREATE my table.</p>

<pre><code>$file = fopen("SGS_Fall_Booklist.csv", "r");
$entry= fgetcsv($file);
echo $entry[0] . $_GET["program"] . $entry[1] . $GET["school"] . 
$entry[2] . $GET["term"];
echo "&lt;br&gt;AutoFill (last years ISBN's)&lt;br&gt;&lt;input id='checkall' type='checkbox' &lt;/input&gt;";
echo "&lt;table&gt;&lt;tr&gt;
     &lt;th&gt;Edit&lt;/th&gt;
    &lt;th class='coursename'&gt;" .   $entry[6] . "&lt;/th&gt;
    &lt;th class='startdate'&gt;" .  $entry[7] . "&lt;/th&gt;
    &lt;th class='booktitle'&gt;" . $entry[17]. "&lt;/th&gt;
    &lt;th class='author'&gt;" . $entry[18]. "&lt;/th&gt;
    &lt;th class='isbn'&gt;" . $entry[16]. "&lt;/th&gt;
    &lt;/tr&gt;";
while(! feof($file))
{
    $entry = fgetcsv($file); 
   echo "&lt;tr&gt;
      &lt;td&gt;&lt;input type='checkbox'&gt;&lt;/input&gt;&lt;/td&gt;
      &lt;td class='coursename'&gt;" . $entry[6] . "&lt;/td&gt;
      &lt;td class='startdate'&gt;" . $entry[7] . "&lt;/td&gt;
      &lt;td class='booktitle'&gt;" . $entry[17]. "&lt;/td&gt;
      &lt;td class='author'&gt;" . $entry[18]. "&lt;/td&gt;
      &lt;td class='isbn'&gt;&lt;/td&gt;
    &lt;/tr&gt;";                                 
}

echo "&lt;/table&gt;";
fclose($file);
</code></pre>
