command php -v is working when I execute simple shell_exec('./script.sh'); but when I use sudo it doesn't work without sudo service stop command is not working.

var_dump(shell_exec('sudo bash ./script.sh')); this command return

sudo: no tty present and no askpass program specified

script.sh

#!/bin/bash
php -v 

sudo service  apache2 stop

command.php

<?php

echo shell_exec('./script.sh');
echo shell_exec('sudo bash ./script.sh');  # not working
?>

ls -la

-rwxr-xr-x  1 www-data root    68 Jun 15 02:24 script.sh

**/etc/sudoers **

sudo visudo
