在命令仍在运行时从php exec()获取结果? [英] Grab results from a php exec() while the command is still running?

问题描述

当我像这样从PHP运行exec时:

When I run an exec from PHP like so:

$result = exec('command');

由此产生的结果将存储在$result中.但是在我目前的情况下，我的命令可能需要花费几分钟并在运行时输出结果.有没有办法在运行时获取输出?我知道passthru方法会将结果输出为浏览器，但实际上我直接想要它.

The results from this will be stored in $result. But in my current case, my command can take a few minutes and outputs results as it is running. Is there a way I can get output while it is running? I know that the passthru method will output the results to be browser, but I actually want it directly.

推荐答案

您应该看看 proc_open

在使输出流成为非阻塞(使用stream_set_blocking)之后，您可以随时读取它，而不会阻塞PHP代码.

After making the output stream non-blocking (with stream_set_blocking), you can read from it whenever you want without having your PHP-code blocked.

-编辑- 如果您使用

$result = exec('command > /path/to/file &');

它将在后台运行，您可以在/path/to/file中读取输出

It will run in the background and you can read the output in /path/to/file
