在PHP中运行shell_exec函数不起作用

Question

run "mumudvb -l" command in the linux terminal has correct output. but in php the output is nothing.like this:

$output = exec('mumudvb -l');

$output = shell_exec('mumudvb -l');

 $output = "" //the output

why this happen?

Answer 1

You cannot use this function because php.ini know it's disabled functions in config file

+Solution: Open your php.ini, find disable_functions and remove your function then restart web server. BTW, becareful because security problem you may have. You should improve your server security
