Hi guys i m trying to view a log file as a html file from my server , i m using one script which is here , so overall i m not a coder just trying to get it work

because log file latest entries are at bottom and it becomes too big after some time, so i was thinking to make something which will show last entries on top ( easy to read ) and it will show only latest 50 entries ( means last 50 entries )

2.
and i need some regular expressions to match and replace URL into link for following types

thanks for help

for the first question to retrieve the data of the log file, there is a command available in linux. You can use that in your php code using any of these functions system, passthru, exec...

The command is something like

tail -f 'your_path_of_logfile'

for more details on tail check
tail --help in linux prompt

I didn't get what we have to do exactly
