Is there an easy way to use wordpress through php-fpm using gwan?
Any use case, example of this to share?
As we never succeeded in making Zend PHP run in a thread-safe manner, there's no way we can advise, unless someone makes a Wordpress port for PH7, which is both supported by G-WAN and thread-safe.
As multicore systems are now the norm (even on embedded platforms), either Zend will finally publicly release a thread-safe PHP, or people will increasingly look for alternatives.
Per the request of 'Nagi', here is the G-WAN PHP module sent to Zend for review:
// ---------------------------------------------------------
// php.c: G-WAN using PHP scripts
// ---------------------------------------------------------
// To build PHP5:
//
// CFLAGS="-O3" ./configure --enable-embed --enable-maintainer-zts
// --with-tsrm-pthreads --without-pear
// make clean
// make
// sudo make install
