this is wat i did..

<html>
<head></head>
<body>
<form>
  <table>
    <tr>      

      <td colspan="2"><img src="logo.jpg"></td>
    </tr>
    <tr>
      <td>Name:</td>
      <td><a href="http://www.yahoo.com">yahoo</a></td>
    </tr>
    <tr>
      <td>Age:</td>
      <td><a href="http://www.google.com">7yrs</a></td>
    </tr>
    <tr>
      <td><a href="http://www.google.com">Location:</a></td>
      <td><a href="http://www.google.com">google</a></td>
    </tr>
    <tr>
      <td>Postal code:</td>
      <td>123467</td>
    </tr>
    <tr>
      <td>Phone:</td>
      <td>987654321</td>
    </tr>
  </table>
</form>
</body>
</html>

$url="content.html";

$content = file($url);
  $regex = @"(http:\/\/([\w.]+\/?)\S*)";

  // count line
  $numLines = count($content);
  // process each line
  for ($i = 0; $i < $numLines; $i++) {

  $line = trim($content[$i]);  
  if (preg_match_all($regex,$line,$matches)) {
    echo $line."<br/>";
    print_r( $matches )."<br/>"; 

  }

  }

the result is

yahoo
Array ( [0] => Array ( [0] => http://www.yahoo.com">yahoo ) [1] => Array ( [0] => www.yahoo.com ) ) 7yrs
Array ( [0] => Array ( [0] => http://www.google.com">7yrs ) [1] => Array ( [0] => www.google.com ) ) Location:
Array ( [0] => Array ( [0] => http://www.google.com">Location: ) [1] => Array ( [0] => www.google.com ) ) google
Array ( [0] => Array ( [0] => http://www.google.com">google ) [1] => Array ( [0] => www.google.com ) )

yahoo, 7yrs, google or location are hyperlinks.. how do i extract the hyperlink or url to a variable??

nuttynibbles

is there a way to read a certain table or row using file()?? i do not wanna read the whole page..

I don't know how you want to handle the links afterwards, but it is possible that you should look into xslt.

it seems that XSLT extract info from xml for later use.. what im lookin for is crawl to a page (which i've already done using file() ) and extract the hyperlink (which i also manage to do). but i wanna select which portion of table to attack.. because currently im extracting all the hyperlink from the entire page..
