php shell_exec实时更新 [英] php shell_exec with realtime updating

问题描述

我有这个要通过php执行的shell程序.问题在于，这可能需要很长时间，因此，我需要对用户的浏览器进行实时更新.

I have this shell program that I want to execute by php. The problem is that it can potentially take a long time, and as of that I need it to have real-time updating to the user's browser.

我读到我可能需要使用popen()来做到这一点，但是我有点(好吧，我的确是:P)一个PHP noob，无法弄清楚如何做到这一点.

I read that I may need to use popen() to do that, but I am sort of (ok, I really am :P) a PHP noob and can't figure out how I may be able to do it.

非常感谢您的帮助！

推荐答案

if( ($fp = popen("your command", "r")) ) {
    while( !feof($fp) ){
        echo fread($fp, 1024);
        flush(); // you have to flush buffer
    }
    fclose($fp);
}
