//I heard that php4 also supports java/EJB.
// this script is come from zend. :)
$Word = new COM("word.application") or die("Unable to instanciate Word
");
PRint "Loaded Word, version {$word->Version}n";
$word->Visible = 1;
$word->Documents->Add();
$word->Selection->TypeText("This is a test...");
$word->Documents[1]->SaveAs("Useless test.doc");
$word->Quit();

Note: Use phpinfo() first to see if your machine has COM support turned on.
