Ubuntu无法在PHP中执行exec（test.sh）

Question

In my php code:

exec(test.sh);

and test.sh has code:

echo "Hi this is test?" | espeak --stdout > demo.wav

But nothing happen. No error, No output.

If i try to execute test.sh from terminal that it will work perfectly. So why it not run on my php.

Can someone help me?

Answer 1

How do you run your PHP script? With php-cli (in shell mode)? HTTP (Apache, ...)?

It could be a path problem. Could you give us the path of your test.sh, the path of your php script or the URI which is called to run the PHP if you use apache or other HTTP server?

Answer 2

apache用户将需要对当前工作目录（大概是包含您的php脚本和test.sh的目录）具有写权限。
