How to set $PATH for php exec or shell_exec

Question

我已经设置了要运行ant的PATH，并且它正在腻子上工作，但是在php exec上却返回了sh ant命令，但我没有尝试通过export PATH = / usr / ant / bin来设置PATH。

Answer 1

在exec之前调用putenv：

putenv('PATH=/usr/ant/bin');

Answer 2

Environment variables are set in the context of a user session. If you want to set the variable for the PHP user you should check what user apache runs under (typically apache), and add

export PATH=/usr/ant/bin

to

/home/apache/.bashrc

So that the path is set for every session the user apache starts.
