I think the things is probably that C programmers are used to dealing
with more primitive entities than high level programmers are.

PHP is designed to hide the detail by and large.

And 'do the memory management for you'

Which is fine, if phps way of managing memory doesn't crap out.

I had exactly te same sort of issues with mysql. I was trying to
normalise a huge database - 2.5M records as a flat spreadsheet type file
with tons of redundant data in it.

The rather complex SQL query that I end up with still hadnt finished
after 8 hours, so I write a program in C to utilise simpler mysql
queries and then step through them and re interrogate the database
instead of using a nested query structure. And show me what it was doing
as it did it.

The program took 45 minutes to write, and ran in another hour.

The point is that languages that second guess the way you want to do
stuff are never as efficient for a single problem as you can be if you
can decide how yourself.

Most of the time they are mote than good enough: Sometimes they are not.

Its the old 'compiled language versus assembler' argument.

99% of the time is a non issue and you trade the speed of writing code
for the speed of running, but sometime it tips the other way

Ineptocracy

(in-ep-toc’-ra-cy) – a system of government where the least capable to
lead are elected by the least capable of producing, and where the
members of society least likely to sustain themselves or succeed, are
rewarded with goods and services paid for by the confiscated wealth of a
diminishing number of producers.
