Your substr thing works, dude. Thanks.

In other words, in my part where I put $header_format = 'Lversion/Lposx/Lposy/Lposz/Sang/Scurrentsector/Snumsectors/x$sectors/Snumwalls'; If I change $sectors to what its literal value is at that point of 14440, it works ok. I don't get it. Can you not use variables inside this expression?

Ok, here is what I got so far. I tested with my C++ program and it checks out ok except the number of walls is wrong. Here is my code <?php #read the file $file = "1hk.map"; $fp = fopen ($file, 'rb') or die ("File <i>$file</i> cannot be opened."); $data = fread ($fp, 500000) or die ("Could not read data from file <i>$file</i>"); #everything up to the number of sectors. $header_format = 'Lversion/Lposx/Lposy/Lposz/Sang/Scurrentsector/Snumsectors'; $header = unpack ($header_format, $data); #now, read the number of walls after the sectors by skipping $sectors = $header['numsectors'] * 40; $header_format = 'Lversion/Lposx/Lposy/Lposz/Sang/Scurrentsector/Snumsectors/x$sectors/Snumwalls'; # Unpack the header data $header = unpack ($header_format, $data); # Display the data stored in $data print_r ($header); ?> Basically, it doesn't seem to like my skipping of the number of sector bytes. But, if I give it the literal number of $sectors, it works ok.

Hi. My example isn't 100% accurate to the file. But, basically, they are .map files. Here is how they start: 4 bytes-version 4 bytes-position x 4 bytes-position y 4 bytes-position z 2 bytes-angle 2 bytes-current sector 2 bytes-number of sectors 40 bytes * number of sectors-the sectors themselves. I attached an example map file. Really, it's just the 40 bytes * number of sectors that I can't seem to wrap my head around. I can see how to read the other stuff with the unpack function.

Hi, guys. I'm trying to wrap my head around trying to read a header in a binary file in php. So, far, I have been able to get the data into a string using file_get_contents. Now, I think I need to use unpack, but it's a bit confusing to me still. For example, my file starts by having a 1 byte version number, 4 bytes to represent a number of walls, then "number of walls" * 40 bytes for the actual walls. But, the problem is, the wall itself is a structure composed of various elements to make up that 40 bytes, from which I'll need to pick out a specific area of interest. I can do this easily in C, but in php. I can't think how to grab the info. Any ideas? Maybe just how to read 1 byte, 4 bytes, then "number of walls" * 40 bytes will get me in the right direction.

Hi, guys. I can't for the life of me figure this redirecting stuff out. Basically, I have 2 domains: http://duke3d.org and http://uschampionshipvball.com. Currently, they both link to the root folder (the public_html) folder. I simply want http://duke3d.org to go to public_html/forum and http://uschampionshipvball.com to go to public_html/vball. Any advice?
