Hi Konstantine, and welcome to PhpDig.net!
Thanks for the contributions too. It's good to have other people review the code and offer input. :)

Hi again, so there IS a bug. I can't explain why is it, but you can see it. Try to index http://madboard.ru and look at the page http://madboard.ru/index.html?act=do&code=43. So you will not find links such as http://madboard.ru/index.html?act=do&code=45. Try it. I didn't found why is it happening. Any sugestions?

I found it (BUG)!!! And it's not in PHPDIG :angel: It's in PHP function :D
I use PHP Version 4.3.3, OS Linux, so the bug is in parse_url function :D
You can find it out on site madboard.ru. If you'll try to index it you'll find about 42 pages (if the bug is in your version of PHP).
So change in robot_functions.php in function function phpdigRewriteUrl($eval)
code:
$url = @parse_url(str_replace('\\\\'"','',$eval));
if (!isset($url['path'])) {
$url['path'] = '';
}
by following code:
$url = @parse_url(str_replace('\\\\'"','',$eval));
$url['query']=str_replace("&","&",$url['query']);
if (!isset($url['path'])) {
$url['path'] = '';
}
After that try to index madboard.ru again :angel:
You'll find about 400 pages!!!
the bug is:
if you try to parse url http://madboard.ru/index.html?act=do&code=43 you'll get in 'query' line act=do&code=43
Any questions? :angel:
If you tried it and it was as I said, please reply on this message :angel:

Hi. Speaking of & versus & there is a small bug in version 1.8.0 when PHPDIG_SESSID_REMOVE is set to true. To fix do the following.
In robot_functions.php find:
$eval = str_replace("&&","&",$eval);
$eval = eregi_replace("[?][&]","?",$eval);
$eval = eregi_replace("&$","",$eval);
and replace with:
$eval = str_replace("&&","&",$eval);
$eval = str_replace("?&","?",$eval);
$eval = eregi_replace("&$","",$eval);
Also, in robot_functions.php find:
$file = str_replace("&&","&",$file);
$file = eregi_replace("[?][&]","?",$file);
$file = eregi_replace("&$","",$file);
and replace with:
$file = str_replace("&&","&",$file);
$file = str_replace("?&","?",$file);
$file = eregi_replace("&$","",$file);
