the main thinking Luuk was that to do what he wanted would invove a lot 
of calls to libraries that are not a standard part of PHP but are a part 
of the C library


Although I stand corrected because get_ppid() does seem to exist in PHP, 
and that's half the battle.


I cant remember the way to programmatically read a process table as ps 
does, but I am fairly sure php doesn't have a function to do it.

Well firstly if you can code PHP its not a huge step to C, especially if 
you have some crib code.

secondly its a shade more secure if you hide passwords and so on inside 
nmunged data.

But my real reason was access to system libaries that dont as a rule 
come with PHP.

Libproc.a is the standard way I believe  to examine the /proc filesystem 
where all this info exists.

In the end its a tradeoff between writing something in PHP to 
interrogate that, and using some pre-existent source code in C

I've had similar issues with certain things where PHP did not handle 
concurrent accesses to certain graphics libraries well. Very strange 
bugs happened. Re wrote it in C and no more problems as I used a 
different graphics library that PHP did not support.

I am a great fan of PHP but there are times when I abandon it because - 
mainly - I need a library it doesn't support.

And I have not yet tackled the issues of writing my own extensions to it.

And although I know you can, I'd rather use shell or C for cron scripts. 
PHP can be used, but for me its strengths lie in its easy merging with 
HTML and mySQL: Althouh even there, I have written database interfaces 
in C easily enough. C just doesn't do outputting of straight HTML the 
way a ?> does ! :-)

I suppose at the end of the day is no big deal to write a massive 
printf() statement, but is more tedious than a ?>
