I'm developing a php application using Linux server. My problem is executing shell_exec() to call some exe file is not work(actually not exe, it's kind of linux executable file)

echo shell_exec("whoami");

I got daemon

echo shell_exec("ls")

I got some filename but

echo shell_exec("php -v")

I got nothing, a blank page

echo shell_exec("php ....bla bla bla")

a blank page too.

All these command if I type on terminal(user hu) will works. I have searched google for several hour, people says that because of permission. I don't have experience on Linux. What do I have to do to execute my program in php?
