If you are new to PHP or just need to refresh your skills, this is the place to start. This series of tutorials will give you the basic knowledge you will need to create a simple PHP website.
PHP is a reflective programming language originally designed for producing dynamic web pages.[1] PHP is used mainly in server-side scripting, but can be used from a command line interface or in standalone graphical applications. Textual User Interfaces can also be created using ncurses.
com_get_active_object() is similar to creating a new instance of a COM object, except that it will only return an object to your script if the object is already running. OLE applications use something known as the Running Object Table to allow well-known applications to be launched only once; this function exposes the COM library function GetActiveObject() to get a handle on a running instance.
progid must be either the ProgID or CLSID for the
object that you want to access (for example
Word.Application). code_page
acts in precisely the same way that it does for the COM class.
If the requested object is running, it will be returned to your script just like any other COM object. Otherwise a com_exception will be raised. There are a variety of reasons why this function might fail, the most common being that the object is not already running. In that situation, the exception error code will be MK_E_UNAVAILABLE; you can use the getCode method of the exception object to check the exception code.
| Warning |
Using com_get_active_object() in a web server context is not always a smart idea. Most COM/OLE applications are not designed to handle more than one client concurrently, even (or especially!) Microsoft Office. You should read Considerations for Server-Side Automation of Office for more information on the general issues involved. |
