How can I use the COM components in php?

Answer :

The COM class provides a framework to integrate (D)COM components into your PHP scripts.
string COM::COM( string module_name [, string server_name [, int codepage]]) - COM class constructor.


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.

$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 = null;
