• What does the $1$2$4 mean in this preg_replace?

  - by Taylor

  Got this function for ammending the query string and was wondering what the replacement part of the pre_replace meant (ie- $1$2$4). function add_querystring_var($url, $key, $value) { $url = preg_replace('/(.*)(\?|&)' . $key . '=[^&]+?(&)(.*)/i', '$1$2$4', $url . '&'); $url = substr($url, 0, -1); if (strpos($url, '?') === false) { return ($url . '?' . $key . '=' . $value); } else { return ($url . '&' . $key . '=' . $value); } } Not too familiar with regular expression stuff. I get the various parts to preg_replace but not 100% about the use of '$1$2$4' in the replacement part.

  while($row = mysql_fetch_row($result)){ preg_match('#<span id="lblNumerZgloszenia" style="font-weight:bold;font-style:italic;">([^<]*)<\/span>#',$row[1],$matches); $query2 = 'UPDATE content_pl SET kategoria_data='.$matches[1].'

• How can I get the file extensions from relative links in HTML text using Perl?

  - by Structure

  For example, scanning the contents of an HTML page with a Perl regular expression, I want to match all file extensions but not TLD's in domain names. To do this I am making the assumption that all file extensions must be within double quotes. I came up with the following, and it is working, however, I am failing to figure out a way to exclude the TLDs in the domains. This will return "com", "net", etc. m/"[^<>]+\.([0-9A-Za-z]*)"/g Is it possible to negate the match if there is more than one period between the quotes that are separated by text? (ie: match foo.bar.com but not ./ or ../) Edit I am using $1 to return the value within parentheses.
