In my component-based solution I used XML streams instead of arrays, but the principle was the same. As a UI, it has been designed to be used within Windows to read and write an Access database file.

In the event on an error this will invoke my standard error handler. The code needed to connect to the Access database then would be similar to: With the techniques shown here, you can generate a spreadsheet -- formulae, formatting, and all -- in a way users expect to see it.

With Officeyou can save your Microsoft Excel spreadsheet as XML and use the file just as you would the binary equivalent.

You can define a class which extends an existing class, thus inheriting all the properties and methods of that class. Windows hosts have a similar folder hierarchy to a Windows PC, so the location of the files on a Windows server will likely have a path of the form C: Connection to Database Before reading or writing a database, a connection must be made to it.

This is done using code similar to the following: How this is used will become apparent later on. Then use the SQL file to create the tables with the required fields. The first Worksheet object contains the real data. You can define a class destructor which is processed when a class instance is terminated.

You can define an INIT operation which is processed when a component instance is created. Import the data The import system starts easily enough with a page in which you specify the input Excel XML file see Figure 3. Place the cell value into a local value associated with that field.Reading Access Databases with PHP and PECL.
