Nonsense. Most of them can be replicated - in practice it's usually not
really worth the effort. I wrote a class to handle posts to pages - when I
benchmarked it was only slightly slower than using the curl extension
(about 30% slower). This replaced a method where the standalone curl
executable was invoked to carry out a post which was 800% slower.
PHP now has a range of process control functions - it does not have direct
access to the device ioctls you'd need for writing low level hardware
drivers but if you really wanted to do that there's not a lot to stop you
writing your own PECL.
It's interesting that a lot of people are now using PHP outside of
web-browsers 0 indeed, there's at least one web_server_ wirtten in PHP.
