I am working on a php script that tries to get the username of the person on a given computer on a server.
Here's the code im using
exec('wmic COMPUTERSYSTEM Get UserName', $user);
print_r($user);
And when ever this runs i always get back Array( )
Any help would be greatly appreciated.
You cannot use exec to return any output from your command.
See this answer.But you can use shell_exec() to return the output of your command.
You can have an array of computer:
$computer = array('comp1', 'comp2');
$comp1 = array();
foreach($computer as $username)
{
$comp1 = shell_exec("wmic /node: ". $username ." computersystem Get UserName");
print_r($comp1);
}
But if there is only one:
$user = shell_exec('wmic /node: <yourcomputername> COMPUTERSYSTEM Get UserName');
print_r($user);
But i suggest to get logged users, there is a tool from sysinternals that i used to do certain task like executing process remotely, list info about the system through command prompt.
Checkout and install PSTools. Then you can use the PsLoggedon.exe
exec always return a array, if the output argument is present
See: http://www.php.net/manual/en/function.exec.php
If your code return only one user, try this:
$user = shell_exec('wmic COMPUTERSYSTEM Get UserName');
echo $user;
shell_exec manual:
http://www.php.net/manual/en/function.shell-exec.php
It may be disabled if PHP is in safe mode.
Look: https://www.php.net/manual/en/features.safe-mode.functions.php
You can check your server's PHP settings with the phpinfo() function.
You have to specify the array this way: print_r($user[1]);
exec('wmic COMPUTERSYSTEM Get UserName', $user);
print_r($user[1]);
