pthreads（四）php7隻支援在cli模式下使用pthreads擴充

1 ERROR!

用php7了，編譯之後安裝好擴充，運行php-fpm的時候報錯，在公司沒有解決，回家在mac上複現這個問題：

[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
Fatal error: The fpm-fcgi SAPI is not supported by pthreads in Unknown on line 0

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

2 WHY?

一直以為這個問題是可能是因為php7不穩定導致的，後來看到百度上有人說php7隻允許CLI模式下使用pthreads擴充，對此半信半疑，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 ;)

以上是作者的原話

3 SOLVE:

CLI模式下，php會優先讀取php-cli.ini，如果沒找到會使用php.ini，SO：

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

【2】編輯原來的php.ini檔案注釋掉pthreads擴充 // ;extension=/..(路徑)../pthreads.so

這樣CLI模式下php-cli.ini生效，而php-fpm不會讀php-cli.ini
