In this tutorial
I will show you how to create a php app that you can run COM objects with
(ie, word etc.). It will run off of your comp and be distributable to
other users.
Ok so what is com?
" COM is an acronym for Component Object Model; it is an object orientated
layer (and associated services) on top of DCE RPC (an open standard) and
defines a common calling convention that enables code written in any language
to call and interoperate with code written in any other language (provided
those languages are COM aware). Not only can the code be written in any
language, but it need not even be part of the same executable; the code
can be loaded from a DLL, be found in another process running on the same
machine, or, with DCOM (Distributed COM), be found in another process
on a remote machine, all without your code even needing to know where
a component resides." --www.php.net
Ok now download this file.
It
contains 4 files:
php4ts.dll
- contains all the php functionality
start comIE.bat - this will start the application
php.exe - this will run the php
comIE.php - this will contain the php code for the app
For fun lets
create an app that will navigate to your email server and log you in.
(mail.com will be my example)
To initiate a new COM object you pretty much only need one line:
$b = new COM("InternetExplorer.Application");
Ok now initiate the properties for this new ie window.
$b->toolbar = 0;
$b->statusbar = 1;
$b->visible = 1;
//navigate to the server
$b->navigate("http://www.mail.com/");
//set some more attributes
$b->document->body->all['login']->setAttribute('value',
'username');
$b->document->body->all['password']->setAttribute('value',
'password');
//submit
the form
$b->document->body->all['Go']->form->submit();
A few useful ie functions
$b->Document->body->innerHTML;
//will return the html of the page
$b->ReadyState // will return current ie readystate
Microsoft
word
Now for some
word stuff:
$word = new COM("word.application");
//show the word app
$word->visible = 1;
//open a new document
$word->Documents->Add();
//add some text to the document
$word->Selection->TypeText("this is some
sample text");
//save the document as sampleword.doc
$word->Documents[1]->SaveAs("sampleword.doc");
//close word
$word->Quit();
//free object resources
$word->Release();
$word = null;
The reaches of COM are pretty much endless. This is just a sample of what
you can do with it. Google it, you'll find tons :).
