Unfortunately PHP was never and will most likely never be threadsafe as a module. (Yes, I know that there's the ZTS code, but hey, are you really serious about this?) I never understood why the core devs never switched to a threaded model, but I believe they never deemed it truly necessary. The ZTS threaded module has a few interesting approaches but fails in some other areas. To be honest, I suggest to use the fpm-cgi SAPI module with an Apache threaded environment. > Does this statement on the PHP website still stand? > http://www.php.net/manual/en/faq.installation.php#faq.installation.apache2 Sorry, didn't read it. > Seems a bit archaic these days to eschew multithreaded environments, > doesn't it? Yes, it is. Doesn't change the fact that PHP is not threadsafe. > More specific questions: > * is there any kind of authoritative list of PHP modules that are NOT > threadsafe? If so, where might I find it? No, there isn't. But if you run php via fpm, it doesn't really matter anyway. > * What warnings, indications, failures, or errors, if any, might I > encounter if I am experiencing undesirable behavior by using PHP in an > event or worker environment? I use an event MPM on my server with an fpm cgi module Cheers, K. C. -- regards Helmut K. C.
