alphabeta12 Posted July 2, 2009 Share Posted July 2, 2009 I am working with files opened by fopen binary. Immediately these files are changed to hex via bin2hex. From there I do some processing of the hex. I have no clue as to how I should write the changes to a new file from that point. Can I get any help with writing hex to a file?The files that I use are pretty much unknown (they are kinda sorta images), and all that you can do to them is edit the hex, and I use PHP to do that.

justsomeguy Posted July 2, 2009 Share Posted July 2, 2009 You can use the pack function to turn an ASCII hex string into binary data, and then use fwrite to write it back to the file. Make sure to use the b flag with fopen to open the file in binary mode. Link to comment Share on other sites More sharing options...
