[PHP-DEV] RESOLVED (sort of): [PHP-DEV] PHP / C++ Interaction
George Schlossnagle sent me the following link to a a tutorial by Jay Smith: http://142.166.76.45/software/php5cpp/php5cpp/ This provides full code for a C++ based extension. On a Suse 9.3 distribution of Php5 this results in an (unresolved) error, but with an Apache2/Php5 build from source, the example is fine. Thanks to all, for responses. Cheers, Andrew.

You could just have the PHP extension written in C++. There is no
requirement of PHP extensions to be written in C, you just need to make sure
you properly wrap the C parts inherited from the core w/ an extern C block.
I have wrapped more than a handful of C++ libraries at my day job in into
PHP extensions using more or less the following approach.
Here's a rough overview of the changes needed (this list might not be
complete, but should be close).
config.m4 changes
-
I set the the compiler environment variables (aka CC and CXX) to both use
g++. Not sure if this is necessary.
In your included libraries (aka PHP_ADD_LIBRARY_WITH_PATH) make sure you
include libstdc++
your source file changes
---
Wrap the following in an extern C like shown below:
extern C {
#ifdef HAVE_CONFIG_H
#include config.h
#endif
#include php.h
#include php_ini.h
#include ext/standard/info.h
#include php_your_extension_name.h
}
And later on further down wrap the following:
extern C {
#ifdef COMPILE_DL_YOUR_EXTENSION_NAME
ZEND_GET_MODULE(your_extension_name)
#endif
}
As best as I can remember, that is all that is necessary to write a C++ PHP
Extension instead of a C one. Brighter minds on this list might know better
if I am forgetting something, but I remember it being very minimal changes
so I think the above is it.

[PHP-DEV] PHP / C++ Interaction
Having got a PHP/C extension .so shared library working, (courtesy this mailing list), and now also ported a C++ data server to Linux, which could also be a (C++) .so, the obvious question is: - can I talk to a C++ library from PHP, either directly or via a PHP/C extension? - aka: is there a 'com'/.Net equivalent on Linux to permit language independent calls ? Trivially possible, trivially impossible, or somewhere in-between? Cheers, Andrew.
