I need to split a few large files on my server into rar files. I am running linux and I know there is some way to do it with PHP but am not very sure is there any help?

Thanks.

install rar and use a system call.

I am not very experienced with code and so on can you bumb it down a bit

PHP Code:

system("rar --whatever_is_needed_as_parameter $srcfile"); 


or something like that.
