You will need to compile or allow the option to execute on the server with in php.
Check to see if php allow the exec command.
<?php
function exec_enabled() {
$disabled = explode(', ', ini_get('disable_functions'));
return !in_array('exec', $disabled);
}
?>
You will need to add executable permissions to the file.
You can then:
<?php
exec("C:\\PATH\\TO\\FILE.exe")
?>
Hope that helps, its not really a very safe thing to have enabled, do not allow users to pass directly to this command.
For more info check the php man pages. http://php.net/manual/en/function.exec.php
