都說php不支持多進程,
那這種場景是不是就不適合php了?如果我要更新一千個數(shù)據(jù)的信息,上傳一個sql文件,然后依次執(zhí)行這樣肯定會很慢,能否在代碼里利用pcntl_相關的函數(shù)來實現(xiàn)多進程處理這個請求呢?
http://php.net/manual/zh/intr...
Process Control should not be enabled within a web server environment and unexpected results may happen if any Process Control functions are used within a web server environment.
At least for PHP 5.3.8 which I am using, and who knows how far back, it's not a matter of "should not", it's "can not". Even though I have compiled in PCNTL with --enable-pcntl, it turns out that it only compiles in to the CLI version of PHP, not the Apache module. As a result, I spent many hours trying to track down why function_exists('pcntl_fork') was returning false even though it compiled correctly. It turns out it returns true just fine from the CLI, and only returns false for HTTP requests. The same is true of ALL of the pcntl_*() functions.
這里面說pcnt對http請求無效,只適用再cli模式下,請問大神,php遇到這類場景,如何處理呢?難道就只能借用其他語言來實現(xiàn)么?
不是說不可以,只有你會不會的問題,swoole可以做這個,用協(xié)程并發(fā)性能很好,php雖然不是最好的語言,但也被低估的語言. 多線程不一定好.
