Hey, I have a simple loop & gather question.

Hello, how would I specify a web page, such as:
www.test.com/list.php

And in this page, there would be hyperlinked images.

Every image has its own unique id, and is used inside the hyper as follows:
http://test.com/page2.php?id=x

So what I want to do, is sort through this page, saving every id into my array variable.

So say the first 2 images had id's 1 & 7, like
http://test.com/page2.php?id=1
http://test.com/page2.php?id=7

I need the script to run through, and gather what is after ?id= , and store it into my variable $id[x];

So I would have: $id[0] = 1; $id[1] = 7; and so on, until it gathers the id from every images hyperlink.

Thanks!

 

I figured something out, but it doesn't loop through the source gathering every id, just the first one it finds.
Here's the code, if anyone could build up on it:

  $start = strpos($find, 'id=', $index);
  if($start)
    {
    $start += 6;
    $index = $start;
    $end = strpos($find, ' ', $start);
    if($end)
      {
      $id = substr($find, $start, $end - $start);
      $index = $end;
      $list[$key] = $id;
      $key++;
      }
  }

Code (markup):

Thanks.

 

Here is something to get you started, this will get all your image links from the page ($html) into $matches...

preg_match_all("/<img src=\"([^']*?)\">/", $html, $matches);
print_r($matches);
