Php shell_exec problem

hello all,

I do not know what i am doing wrong. When i run this if statement i get "Wrong!" all the time.

Regards.

    if(trim(shell_exec('wmic diskdrive get model')) != "Model Maxtor 6Y080L0")
    {
    echo "Wrong!";
    }else{
    echo shell_exec('wmic diskdrive get model'); // Model Maxtor 6Y080L0
    }

PHP:

i tried this way but still not working.

$output = shell_exec('wmic diskdrive get model');
$newoutput = trim($output);
$pieces = explode(" ", $newoutput, 2);
echo $pieces[1]; // Maxtor 6Y080L0

if ($pieces[1] != "Maxtor 6Y080L0"){
echo "wrong";

PHP:

 

ok. the problem was the line break which you can not see on browser. but if you run the code on windows i got this:


Model
Maxtor 6Y080L0


but when i echo with php i had this output:

Model Maxtor 6Y080L0

$output = shell_exec('wmic diskdrive get model');
$pieces = explode("\r\n", $output, 2);

if (trim($pieces[1]) != "Maxtor 6Y080L0"){
echo "Wrong";
}else{
echo "OK.";
}

PHP:

 

For the next time, if you don't want this happening again, always make sure to view the page source, or put <pre> tags around your output so you'll see it as-is in the brwoser.
