How to call Access database and COM program through ADO in PHP_PHP Tutorial

PHP4 already supports Microsoft's COM technology. However, there is very little mention in the COM part of the document.
Here are a few examples I’ve tried. Hope this gives you some idea. Note that these can only run on the 32-bit Microsoft
Windows platform.
Activate ADO with php
ADO is Microsoft's database object technology. ADO includes objects that connect to the database, recordset objects that return data from query statements, and field objects that represent data elements.
Many databases do not directly support ADO. Instead, many databases support two lower levels of Microsoft database technology: ODBC and OLEDB. Many databases support ODBC; but OLEDB has a reputation for being faster than ODBC.
ADO is an API that wraps ODBC and OLEDB.
This example opens a new ADO connection object, opens a traditional ACCESS database through ODBC, and then we execute a SQL query, which will return a recordset object. Then we display the first three fields of the recordset.

$dbc = new COM("ADODB.Connection");
$dbc->Provider = "MSDASQL";
$dbc->Open("nwind");
$rs = $dbc->Execute("select * from products");
$i = 0;
while (!$rs->EOF) {
$i += 1;
$fld0 = $rs->Fields(0);
$fld1 = $rs->Fields(1);
$fld2 = $rs->Fields(2);
print "$fld0 ->value $fld1->value $fld2->value
";
$rs->MoveNext();
}
$rs->Close();
?>

Call Microsoft Word with PHP
Here is another example:

$word=new COM("word.application") or die("Cannot start Microsoft Word ");
print "Loaded word version ($word->Version)";
$word->visible = 1;
$word->Documents->Add();
$word ->Selection->Typetext("This is a test");
?>
