如何制作一个小的PHP链接“蜘蛛”并提取数据？

Question

I want to spider a simple white website that has lot's of html links that represent a phone number' name and address. From each page i want to extract the exact 3 fields that are between the 3 TD's such as:

    <div id="idTabResults2" align="center">
        <TABLE border='1'>
    <tr><th>Name</th><th>Adress</th><th>Phone number</th></tr>
    <TR>
          <TD>Joe</TD><TD>New York</TD><TD>555999</TD></TR>
    </TABLE>

    </div>

So in the example above i would get "Joe", "New York" & 555999. I'm using php and mysql later to insert every result to my DB. Can someone point me to the right direction on how to go about this?

Maybe a faster (and simpler) way than PeeHaa's solution:

• Retrieve the page using file_get_contents()
• Parse it with Simple DOM Parser

For instance:

<?php
require("simple_html_dom.php");
$data = file_get_contents(YOUR_PAGE_HERE);
$html = str_get_html($data);
$tds = $html->find('td');

foreach ($tds as $td) {
  // Do something
}
?>
