While learning to use the Amazon SimpleDB services I looked for a sample PHP program. I could not get the one Amazon provides to work. Dan Myers’ wrote a SimpleDB PHP class but there was no sample code to use it.

This is a collection of small programs that use Dan Myers’ SimpleDB PHP class.

This is a very simple set of examples of working with the Amazon SimpleDB. It is written on top of Don Myers’ SimpleDB PHP class.

* listdomains [list all domains]
* createrecord (single) and domain tag [check if the "tag" domain exists and if not create, then create a record]
* getrecord (single) in domain tag [list that specific record]
* deleterecord (single) in domain tag [delete that specific record]
* createrecords and domain tag [bulk load records]
* listrecords in tag [list all records in tag domain]
* deletedomain tag [delete tag domain]

To install, configure config.inc.php with your awsAccessKey and awsSecretKey.
Copy to the host. Run index.php

Note: An important concept with SimpleDB is Eventually Consistent. This means when you update, add or delete a record you will not see it immediately. This is why the programs are broken into small programs, to give the system time to reflect the updates.
