How can PHP scripts interact with Microsoft Word applications effectively?

PHP scripts can interact with Microsoft Word applications effectively by using the COM extension in PHP to control Word through its COM interface. This allows PHP scripts to create, modify, and manipulate Word documents programmatically.

$word = new COM("word.application") or die ("Could not initiate Word application.");
$word->Documents->Add();
$word->Selection->TypeText("Hello, World!");
$word->Documents[1]->SaveAs("C:\\path\\to\\file.docx");
$word->Quit();
$word = null;
