On a server Apache which runs PHP, I have a command which always return null.
exec("az storage container exists --account-name $accountName --account-key $key --name $containeurName", $output);
I modified the sudoers file but it didn't change anything:
www-data ALL=(ALL) NOPASSWD: /usr/bin/az
Thanks for your help.

Use exec($your_command, $output, $error_code)
and see what $error_code
contains. It may just be because az
isn't in the PATH env variable in PHP.
Try to put the full path to your executable, typically something like this:
<?php
// A default path in case "which az" doesn't work.
define('AZ_DEFAULT_PATH', '/usr/bin/az');
// Find the path to az with the "which" command.
$az_path = exec('which az');
if ($az_path === false) {
$az_path = AZ_DEFAULT_PATH;
}
// Sanitize your variables to avoid shell injection and build the command.
$cmd = $az_path .
"storage container exists --account-name $accountName " .
"--account-key $key --name $containeurName";
$last_line = exec($cmd, $full_output, $error_code);
// Then check if $last_line !== false and check $error_code to see
// what happened.
var_export([
'$cmd' => $cmd,
'$last_line' => $last_line,
'$full_output' => $full_output,
'$error_code' => $error_code,
]);
