Re: [PHP-DEV] How to embed PHP5 into multi-threaded C app?

[Bob Beaty]

Which is my concern.
I've looked at the code differences, and it appears that this 
modification works for running different source files through the 
engine, but I'm concerned about the safety of zend_eval_string() if I 
initialize the engine in one thread and then try to have several 
threads calling zend_eval_string() on different strings.

I'm not convinced that simply making the php_embed_module thread-local 
is going to work either. I'm concerned that the engine was written with 
the idea that only one thread can be initializing the php_embed_module 
and making calls to zend_eval_string(). If this is the case, then I'd 
have to re-write a lot more than php_embed.c to get thread-safety out 
of the engine.

Or am I on the wrong track?

replace the code in php_embed with them, make sure you compile with 
the zts enabled, and the macros's are similar to the original embed 
(use threaded start call at application start up, and thread start 
/start end within the pthread_start(...callback..) method
Thread safeness is not a problem for a single thread.
The problem is to call user functions from different threads
(tsrm_ls pointed to somewhere in different threads, global vars etc 
are not protected).
