If this script will only ever be run on Windows servers, you can use the
Windows-specific shell capabilities through the COM interface.
$shell = new COM("WScript.Shell") or die("This thing requires Windows
Scripting Host");
$shell -> Run($commandinquotes,$windowstate,$wait);
Replace $commandinquotes with your commandline that you want to run. Put
it in single quotes. Replace $windowstate with 1, 2 or 3 for normal DOS
window, minimized or maximized and $wait with 0 in your case because you
don't want PHP to wait for the process to finish.
You could abstract it further by turning the COM "Run" into your own
function. The below code hasn't been tested.
function win_exec($command, $windowstate, $wait) {
$shell = new COM("WScript.Shell") or die("This thing requires Windows
Scripting Host");
$shell -> Run($commandinquotes,$windowstate,$wait);
}
$command = getenv("COMSPEC").' /c c:\mysql\bin\mysql.exe <
> E:/Inetpub/wwwroot/update/load_logs.sql >
> E:/Inetpub/wwwroot/update/load_logs.log';
win_exec($command, "2", "0");
