Php versions – Check if npm plugin exists with php exec

I have simple PHP script for checking npm and npm plugin. It works well via command line, but partially with php exec.

$errors = '';
$outPut = null;
$exitCode = null;
exec('npm -v', $outPut, $exitCode); //<- this works
if($exitCode !== 0) {
    $errors = 'npm is not installed!';
    return false;
}
$outPut = null;
$exitCode = null;
exec('lessc -v', $outPut, $exitCode); //<- this works
if($exitCode !== 0) {
    $errors = 'lessc is not installed!';
    return false;
}

//check version of plugin: npm view/info less-plugin-autoprefix version
$outPut = null;
$exitCode = null;
exec('npm info less-plugin-autoprefix version', $outPut, $exitCode); //<- this not works !!!, $exitCode is 7 and $outPut is empty
if($exitCode !== 0) {
    $errors = 'lessc plugin autoprefix is not installed!';
    return false;
}

All works except command ‘npm info less-plugin-autoprefix version’. As I said in command line it will return excepted correct result.
Anything wrong with my code?

Using exec command npm info less-plugin-autoprefix version 2>&1 produce:

)

Is it possible to fix it programatically?
I dont know if its some problems but in command line 'npm info less-plugin-autoprefix version' works well without errors.

    After some experiments I got working solution. Problem is that Windows platform work different.

    $c = get_defined_constants();
if(isset($c['PHP_OS']) && (strtoupper($c['PHP_OS']) === 'WINNT' || strtoupper($c['PHP_OS']) === 'WIN32')) {
    define('OS', 'WIN');
}
else {
    define('OS', 'LIN');
}
function array_search_partial($arr, $keyword) {
    foreach($arr as $index => $string) {
        if (strpos($string, $keyword) !== FALSE)
            return $string;
    }
}

$outPut = null;
$exitCode = null;
$appdata = getenv('APPDATA');
if(!$appdata) {
    if(OS === 'WIN') {
        $paths = $_SERVER['PATH'];
        if($paths) {
            //C:Usersmy_user_nameAppDataRoamingnpm
            $userPath = array_search_partial(explode(';', $paths), 'AppDataRoamingnpm');
            $userPath = mb_substr($userPath, 0, -4);
            putenv("APPDATA=$userPath");
        }
    }
    else {

    }

}

    then command:

    exec('npm info less-plugin-autoprefix version', $outPut, $exitCode);

    works as expected.

    Redirect the error output to the standard output :

    npm info less-plugin-autoprefix version 2>&1

    This way, the errors will be available in the $outPut array too
