Brigitte Jellinek did a very good talk at the German Perl Workshop
comparing perl and php. I forwarded her Simon's message, and she's
kindly answered some of the questions he asked. I hope that this is
useful.
It seems that I have failed to assimilate her onto the london.pm list. :-(
This time. Muahahahahaha.

I've tried to answer Simons message below, feel free to
forward it.

the only URLs I remember giving are
http://www.php.net <-- general php site
http://perlwelt.horus.at/ <-- my perl stuff
http://phpwelt.horus.at/perl/ <-- sample programs from the talk

you don't even need the chmod. *.php files don't need execute
permissions to be interpreted by mod_php.

that's one of the reasons why installing php apps is so simple.
my understanding is:
in php there is a clear seperation of
a) extentions to the php engine - only these are written in c
b) php applications - written in pure php, no c at all
ad a) Extentions are installed and configured centrally,
and available as binaries. they can only be installed
by person running the webserver. php comes with a long
list of extentions, so there isn't much need for
installing them later on.
ad b) There are practically *no* libraries written in php that
are installed centrally so that they can be used by
several applications. They are trying to set up PEAR,
an imitation of CPAN, http://pear.php.net/
but all the successfull applications
out there don't use it (yet).
so installing an applications never concerns anything outside
it own directory. no make, no c-compiler, no perl^H^H^H^Hphp
header files, no modules needed.
