Subject: PHP footprint and sharing code among SAPI binaries
From: eugenesan@gmail.com (Eugene San)

Hi all,


I want to raise a discussion on subject that is very important for PHP 
usage on Embedded platforms.

I am myself working on projects where we use PHP to manage embedded 
devices. Everything was fine but lately the need to work from flash 
memory appeared.

We discovered that PHP binaries are linked statically with whole PHP 
functionality and there is huge overhead when several SAPI modules used 
on same system.


I have few question I hope to get answers on or ideas for:


1) Is there any reason to link all PHP SAPI modules statically with all 
PHP objects?

2) Is it possible to extract all shared functionality to shared object 
and links all SAPI modules against it?

3) Next issue is XML with DOM support, we where using LIBXML2 but that 
costs ~2.5MB are there there options for supporting that?


Maybe someone already addressed footprint problem and has any kind of 
solutions for that?

Please, any kind of information will helpful here.


Thanks ahead.
