COM 类构造函数。参数:

module_name

被请求组件的名字或 class-id。

server_name

例子 1. COM 示例 (1)

// 启动 word
$word = new COM("word.application") or die("Unable to instanciate Word");
print "Loaded Word, version {$word->Version}\n";

//将其置前
$word->Visible = 1;

//打开一个空文档
$word->Documents->Add();

//随便做些事情
$word->Selection->TypeText("This is a test...");
$word->Documents[1]->SaveAs("Useless test.doc");

//关闭 word
$word->Quit();

//释放对象
$word->Release();
$word = null;

例子 2. COM 示例 (2)

$conn = new COM("ADODB.Connection") or die("Cannot start ADO");
$conn->Open("Provider=SQLOLEDB; Data Source=localhost;
Initial Catalog=database; User ID=user; Password=password");

$rs = $conn->Execute("SELECT * FROM sometable");    // 记录集

$num_columns = $rs->Fields->Count();
echo $num_columns . "\n";

for ($i=0; $i < $num_columns; $i++)
{
    $fld[$i] = $rs->Fields($i);
}

$rowcount = 0;
while (!$rs->EOF)
{
    for ($i=0; $i < $num_columns; $i++)
    {
        echo $fld[$i]->value . "\t";
    }
    echo "\n";
    $rowcount++;            // rowcount 自增
    $rs->MoveNext();
}

$rs->Close();
$conn->Close();

$rs->Release();
$conn->Release();

$rs = null;
$conn = null;
