Hi, I’m working on a score system for a game. The piece of code underneath checks if a player stopped playing while the game was not yet finished (after 1 hour of no progress) and the exit button in the game wasn’t used to quit. This is to splice the player from the datafile. The code...

I have this perl score_board script that I use for a game. It shows the final result of a player. I’m trying to change the script in a way that the score board is immediately updated with the scores of the separate parts within the game. To accomplish this I added $ref to each record which is a...

Hi guys, I’m looking for a regex solution for this: I would like to check if the contents of a $ matches part of the contents of another $. If so proceed with the next action. Example: $one = “regular expressions”; $two = “I would like to know more about regular expressions”; match is...

Hi, I'm trying to maintain a log file. Actually I thought it was working fine but there is a little problem: Each time the script writes to the file it continues on the same line while it should start at a new line. This is the piece of script that I use: $download_log =...

Hi, I have a page where people have to fill in personal details before they can download some files. The idea is to keep a log file from those who downloaded the files. As I’m not at all good with Perl I succeeded at my surprise to get most of this to work! But there is one thing I can’t...

Hi,<br><br>All of this is rather new to me although I think I have overwon the first step and I’m starting to like this. What I’m trying to do is executing a cgi script which should read a datafile and only add 1 to the value of the corresponding variable in the datafile that was send with the...
