dl is definitely interesting, but I'm worried that runtime invocation
might mean performance hits. Is there a way to do load/startup time
inclusion?
you could put it in your php ini file
extension = "foo.so"
then I believe the impact will be on the first instance for that php
engine. so in fastcgi mode, you'd only have the hit once every
PHP_FCGI_MAX_REQUESTS when the child restarts...
Have a look at a standard Mandriva or Fedora/CentOS PHP install. You'll
see that the various parts of the PHP engine are all very modular with
several PECL modules pre-built for your convenience.
The php.ini file is split into files in /etc/php.d/*.ini so that the
packages can put their own little config systems into the php.ini "file"
without dicking around with automated editing.
When using PHP as a module the impact is pretty low, only once per
restart. As Mike wrote the low impact is also apparent in FCGI mode too
(but it's a bit more obvious where the extra load it creates is manifested).
Personally, the convenience of modularity sells this approach for me. I
do generally roll my own RPMs to keep things up to day and patched, but
again I just use that format/deployment method as it's convenient.
