help with regular expressions

[Anon]

hi, i'm having the following problem: i'm having a code snippit that searches a text for links and makes them clickable...
i'm using the following:
$entry_comment = ereg_replace("http://(([A-Za-z0-9.-])*)([a-zA-Z0-9])", "<a href=\"\0\" target=\"_blank\">\0</a>",$entry_comment);

now, the problem is that it works very well with a http://www.whatever.com address

but it fails on links like:
http://www.geocities.com/test
where it will output:
<a href="http://www.geocities.com" target="_blank">http://www.geocities.com</a>/test

now, i can only find other pieces of code that do the same like mine (failing on links with a directory included), but i can't find code that does that second example well too...
so if anyone can help me changing my piece of code, or has another snippit that would work well...that would be great...

thanks in advance,
bert

Please <B>search</B> before posting...this was covered in a previous thread not to long ago.

ereg_replace("http://(([A-Za-z0-9.-])+)([a-zA-Z0-9])((/(([a-zA-Z0-9]))))((.([a-zA-Z0-9])+)*)", "<a href=\"\0\">\0</a>",$search_text);

i searched but could not find that one which works with directories too...when you use the word link in your search you get 100's of results...sorry to not be able to find that particular one that works...
thanks anyway...

try it:
$entry_comment = ereg_replace("http://(([A-Za-z0-9./-])*)([a-zA-Z0-9])", "<a href=\"\0\" target=\"_blank\">\0</a>",$entry_comment);
