usual functions for getting acess to the shell dont work

manpreet Best Answer 2 years ago

I am new to PHP (and Linux) and I don't understand why I can't get access to the shell.

I installed xampp and checked that the variable disabled_functions in the php.ini file does not contain any of the functions from the code below (system, passthru, exec, shell_exec).

Nevertheless, the code below has no impact (not creating any file AND not giving me any error message).

what am I doing wrong?

php
echo system('cd');
echo system('touch TESTACESSCOMMANDLINE.txt', $output);

echo passthru('cd');
echo passthru('touch TESTACESSCOMMANDLINE.txt');

echo exec('cd');
echo exec('touch TESTACESSCOMMANDLINE.txt');

echo shell_exec('cd');
echo shell_exec('touch TESTACESSCOMMANDLINE.txt');

echo 'control
';
?>
