PHP Exec:无需等待，无需丢弃输出，无需nohup [英] PHP Exec: Without Waiting, Without Discarding the Output, Without nohup

问题描述

我需要像这样在PHP中运行命令:

I need to run a command in PHP like this:

exec('dosomething > saveit.txt');

除了我不希望PHP等待它完成.我也不想丢弃输出，也不想使用nohup，因为我将其用于同一目录中的其他内容.

Except I don't want PHP to wait for it to be complete. I also don't want to throw away the output, and I don't want to use nohup because I'm using that for something else in the same directory.

我还尝试了pclose(popen('dosomething > saveit.txt','r'));，但没有成功，它仍然在等待.

I also tried pclose(popen('dosomething > saveit.txt','r')); and that didn't work, it still waited.

推荐答案

向其中添加&符命令的结尾，所以:

Add an ampersand to the end of the command, so:

exec('dosomething > saveit.txt &');
