Figure 15-2. Using Word’s macro language to expose OLE COM objects and parameters assumed syntax for the object method (in our case, Selection.Find.Execute( )). Then right-click in the parameter area to bring up the list of all parameters for the method, as shown in Figure 15-3. 4. Values not in bold are optional in Word macros. PHP requires all values to be passed explicitly, however. 5. Finally, convert the VBScript to corresponding PHP COM function calls, as shown here: 362 | Chapter 15: PHP on Windows This is the Title of the Book, eMatter Edition Copyright © 2002 O’Reilly & Associates, Inc.

Figure 15-3. Gleaning syntax from Word’s online help In this code, we open up Word as an application. We then create a new document and set visible to 1 to make it easier for us to debug. ClearFormatting ensures that unwanted formats aren’t included as criteria in a find or replace operation. Selection->Find->Execute performs our search and replacement, replacing all values of “test” with “rest”. Completing a Word Document Because of the many versions of Word, and PHP’s evolving COM support, the previous example isn’t guaranteed to work in your environment. One way to work around this is to move as much of the automation as possible into the OLE application. So let’s assume we have the invoice shown in Figure 15-4 that we wish to fill in with data from PHP. The basic idea is that we want to traverse the document and fill in the appropriate data. To accomplish this, we will use Word’s bookmarks to move to key locations in the document. To place a bookmark, simply open an existing document, place the cursor in the desired location, and select Insert ➝ Bookmark. In the pop-up window, type in a name for the bookmark and press the Add button. Create bookmarks on the customer address line and in the delivery, item, and total fields. The names of those bookmarks should be customer, delivery, item, and total, respectively. To move to a bookmark directly in PHP, we can use: $word->Selection->Goto(what, which, count, name); This is the Title of the Book, eMatter Edition Copyright © 2002 O’Reilly & Associates, Inc.
