converting link format to work with preg_match_all

[tianshiz]

Hi,

I'm trying to use preg_match_all with this link:

...profile.cfm?id=35278&instance=2010%2D06%2D05%2016%3A00%3A00%2E0&y=2010&m=6&d=18&show=future

However, I'm not getting a match. But if I go to that link through the browser, it automatically turns into:

profile.cfm?id=35278&instance=2010-06-05%2016:00:00.0&y=2010&m=6&d=18&show=future

Running the above link with preg_match_all works, no idea why this is the case.
The only part that changed is the instance in the link, could someone tell me what function was used here? Even chrome could "decode" the link when I simply roll over it.

Thanks for the help,

Tianshiz

it is to do with html entity replacements.

/**
 * function to parse links
 * 
 * params $text string:  the block of text to be parsed
 *
 * returns false: no matches
 * returns array of arrays with each array having the matched url, the query parameters retrieved (as an associative array) and the fragment, if any
*/
function recogniseLinks($text){
  $return = array();
  $pattern = '/(profile.cfm\?.?*) /ims';
  $text = html_entity_decode($text);
  $r = preg_match_all($patttern, $text, $matches);
  if (!$r) return false;
  foreach ($matches[1] as $match):
     $var['url'] = $match;    
     $url = parse_url($match);
     $vars = explode ('&', $url['query']);
     $var['params'] = $vars;
     $var['fragment'] = empty($url['fragment') ? '' : $url['fragment'];
     $return[] = $var;
  endforeach;
  return $return;
}
