PHP run executable file in the xampp of Windows

There is the document talk about this -- http://php.net/manual/en/function.exec.php
<?php function execInBackground($cmd) {
    if (substr(php_uname(), 0, 7) == "Windows"){
        pclose(popen("start /B ". $cmd, "r")); 
    }
    else {
        exec($cmd . " > /dev/null &");  
    }
} ?> 

And there is also another document talk about this -- http://www.somacon.com/p395.php.  In this document , it provide many methods to do this.  And after my try,   pclose(popen("start /B ". " c:\\new\\New2.bat", "r")); is workable.
