I've noticed a really confusing fact.
MD5_file and shell md5sum gives different checksums in some cases.

I've written a complete file integrity check in php.
O was using md5sum from shell to calcullate md5 checksums. After switching to md5_file i've got allerts in some files.
So I made some test, and found, that in some cases md5sum and md5_file gives different output !!!
on my /usr/lib directory I've got 6 differences.

Reproduce code:
shell_exec("/usr/bin/md5sum $currentfile");

We are sorry, but we can not support PHP 4 related problems anymore.
Momentum is gathering for PHP 6, and we think supporting PHP 4 will
lead to a waste of resources which we want to put into getting PHP 6
