php shell_exec with realtime updating

由 断了今生、忘了曾经 提交于 2019-11-27 18:34:26
问题 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. 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. Would appreciate any help! 回答1: if( ($fp = popen("your command", "r")) ) { while( !feof($fp) ){ echo fread($fp, 1024); flush(); // you have to flush buffer }

For example, for unzipping a file or compressing a folder (with tar command), which one is preferred (probably from performance point of view)? UPDATE: In another question, I found a very useful link describing different aspects for these functions. I share the link here, as other may use to better understand
