php - rsync progress doesn't work as expected

Question

I'm using

system('rsync --progress ssh '.$localZip.' user@server:'.$remoteZip);

It starts out saying "filename.zip", but then my page just says loading over and over, and then suddenly at the end it spits out all the progress data. Shouldn't it spit out that data as it goes? It's an 89MB file.

Answer 1

看ob_flush()而不是正常flush()的，因为后者在浏览器中没有影响。
