--------------EDIT------------------------
So i am going with the DOM approach. Here is what I have so far:
<?php function getdata(){
$contents = file_get_contents('internatdata.htm');
//create a DOM based off of the string from the html table
$DOM = new DOMDocument;
$DOM->loadHTML($contents);
//get all tr and td
$items = $DOM->getElementsByTagName('tr');
$tds = $DOM->getElementsByTagName('td');
function tdrows($elements){
$str = "";
for ($ii =0; $ii < $elements->length; $ii++){
$str .= $elements->item($ii)->nodeValue . ",";
}
return $str;
}
for ($i = 0; $i < $items->length; $i++){
echo tdrows($tds) . "; <br />";
}
}
?>
The issue I am having is that I only want to select the td's from each table row. I am trying to achieve this with a nested loop. unfortunately It is printing the text of every tag on the page how ever many times as there are tags. how can i get it so its only printing the td of each tr and not every td on the dom?
I need to use an html table as the source of my data because I don't have access to the database. I figure to be able to query data from the html table I need create a function to convert the table into an array, or a multidimensional array.
I have the basic Idea I think but I need some help finishing the code to return an array based off the html table.
Also If you have a better way of doing this other than converting the table to an array then please let me know
Here is the idea I had so far:
<?php
function getdata(){
$contents = file_get_contents('data.htm');
//add delimiters (semicolon for a row and comma for a cell) ???
$stripped = strip_tags($contents);
//explode into an array based off the delimiters above ???
}
?>

I've updated your edit to fix it.
function tdrows($elements)
{
$str = "";
foreach ($elements as $element) {
$str .= $element->nodeValue . ", ";
}
return $str;
}
function getdata()
{
$contents = "<table><tr><td>Row 1 Column 1</td><td>Row 1 Column 2</td></tr><tr><td>Row 2 Column 1</td><td>Row 2 Column 2</td></tr></table>";
$DOM = new DOMDocument;
$DOM->loadHTML($contents);
$items = $DOM->getElementsByTagName('tr');
foreach ($items as $node) {
echo tdrows($node->childNodes) . "<br />";
}
}
getdata();

You should consider using XML.
It is much easier than HTML table and much more sufficient.

One way to make this easier is to use a dom parser http://simplehtmldom.sourceforge.net/ .
You are still going to have to extract the information into an array but this will make it easier to iterate through the elements one by one.
