# COM

(unknown)

COM -- COM class

## Synopsis

    $obj = new COM("server.object")

## Description

The COM class provides a framework to integrate (D)COM components into your php scripts.

## Methods

``string COM::COM` (string module_name [, string server_name [, int codepage]])`

COM class constructor. Parameters:

module_name

  name or class-id of the requested component.

server_name

  name of the DCOM server from which the component should be fetched. If `NULL`, `localhost` is assumed. To allow DCOM `com.allow_dcom` has to be set to `TRUE` in `php.ini`.

codepage

  specifies the codepage that is used to convert php-strings to unicode-strings and vice versa. Possible values are `CP_ACP`, `CP_MACCP`, `CP_OEMCP`, `CP_SYMBOL`, `CP_THREAD_ACP`, `CP_UTF7` and `CP_UTF8`.

Example 1. COM example (1)
    // starting word
    $word = new COM("word.application") or die("Unable to instanciate Word");
    print "Loaded Word, version {$word->Version}\n";

    //bring it to front
    $word->Visible = 1;

    //open an empty document
    $word->Documents->Add();

    //do some weird stuff
    $word->Selection->TypeText("This is a test...");
    $word->Documents[1]->SaveAs("Useless test.doc");

    //closing word
    $word->Quit();

    //free the object
    $word->Release();
    $word = null;

Example 2. COM example (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");    // Recordset

    $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++;            // increments rowcount
        $rs->MoveNext();
    }

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

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

    $rs = null;
    $conn = null;
