shell_exec doesn't seems to execute

[shelbytll]

The DocumentRoot is /var/www/html
And my web application is /var/www/html/webapp
I tried to execute a program from the webapp directory using shell_exec() but seems like it did not process. Is there anythiing I need to change in php.ini?

try using other cmds like exec, system or passthru

eg:

$output = exec("myprog 2>&1",$outarray);
echo $output . "\n";
for ($i=0; $i < sizeof($outarray); $i++)
{
  echo $outarray[$i] . "\n";
}
