怎样在PHP中通过ADO调用Access数据库和COM程序
PHP4已经支持Microsoft的COM技术。然而文档中在COM部分却提得很少。
这儿是几个我试过的例子。希望这些给你一些概念。注意的是这些只能运行在32位的Microsoft
Windows平台下。
用php激活ADO
ADO是Microsoft的数据库对象技术。ADO里面包括连接数据库的对象,从查询语句中返回数据的记录集对象和表现数据元素的字段对象。
许多数据库不直接支持ADO.代之的是很多数据库支持低两级的Microsoft数据库技术:ODBC和OLEDB.许多数据库支持ODBC;但OLEDB有比ODBC更快的名声。
ADO则是包装ODBC和OLEDB的API.
这个例了打开一个新的ADO连接对象,对过ODBC打开一个传统的ACCESS数据库,然后我们执行SQL查询,会返回一个记录集对象。然后我们显示记录集的前三个字段。
$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();
?>
用PHP调用Microsoft Word
这是另一个例子:
$word=new COM("word.application") or die("Cannot start Microsoft Word");
print "Loaded word version ($word->Version)";
$word->visible = 1 ;
$word->Documents->Add();
$word->Selection->Typetext("This is a test");
?>
