Take a look at OpenEXR. It's probably the best source of information about this format.

Coming from the Java land, I have been searching for a method similar to DataOutputStream.writeUTF() for the last couple of days.

Your tip on the PHP pack() method solved my problem.

Thanks!

Another very useful tool is bin2hex() if you’re looking to get hex data from the binary file.

That is great! Thank you very much for posting this as it is exactly what I was looking for. Nowhere else, including _PHP in a Nutshell_, does anyone mention this critical fact when working with binary data.

Sorry, I don’t know what type of data .cgh files contain and I couldn’t find this extension at http://filext.com/file-extension/chg … I’m afraid I can’t help you in this case.
