Hi, For a project of mine I had to have an embedded webserver with php support. For this I've used the boost::asio multi-threaded example as a base and modified it so I could enable php scripting support. The first, logical and fast thing to do was to try out the embed sapi module but I found it to hang on concurrent php_embed_init calls. The biggest issue I found was that the embedded module bundles sapi module startup and request startup. I ended up writing my own SAPI module as I also needed full support for POST methods, URL queries, etc. but I can imagine people being interested in having an embedded sapi which separates module startup/shutdown and request startup/shutdown so concurrency works together with being able to have separate request environments for each thread. Separating these calls would allow for the following: At program startup initialize the php environment At each thread startup initialize a php request environment With a few minor alterations I could convert my specific sapi module or current embed module to a generic embed-mt multithread capable module. Would this be something that you are interested in? kind regards, Bas van Beek
