pthreads（四）php7只支持在cli模式下使用pthreads扩展

1 ERROR!

用php7了，编译之后安装好扩展，运行php-fpm时报错，在公司没有解决，回家在mac上复现：

[24-Mar-2016 23:06:50] NOTICE: PHP message: PHP Fatal error:  The fpm-fcgi SAPI is not supported by pthreads in Unknown on line 0<br /><b>Fatal error</b>:  The fpm-fcgi SAPI is not supported by pthreads in <b>Unknown</b> on line <b>0</b><br />

[24-Mar-2016 23:06:50] NOTICE: PHP message: PHP Fatal error:  Unable to start pthreads module in Unknown on line 0<br /><b>Fatal error</b>:  Unable to start pthreads module in <b>Unknown</b> on line <b>0</b><br />

2 WHY?

 一直以为这个问题是可能是因为php7不稳定导致的，后来看到百度上有人说php7只允许CLI模式下使用pthreads扩展，对此半信半疑，好吧，上github看看：

pthreads v3 is restricted to operating in CLI only: I have spent many years trying to explain that threads in a web server just don't make sense, after 1,111 commits to pthreads I have realised that, my advice is going unheeded.

So I'm promoting the advice to hard and fast fact: you can't use pthreads safely and sensibly anywhere but CLI.

Thanks for listening ;)

以上是作者的原话

3 SOLVE:

CLI模式下，php会优先读取php-cli.ini，如果没找到会使用php.ini，SO：

【1】cp php.ini php-cli.ini // extension=/..(路径)../pthreads.so

【2】编辑原来的php.ini文件注释掉pthreads扩展 // ;extension=/..(路径)../pthreads.so

这样CLI模式下php-cli.ini生效，而php-fpm不会读php-cli.ini
