| 9 | * Backend for personal addressbook stored in a database, |
| 10 | * accessed using the DB-classes in PEAR. |
| 11 | * |
| 12 | * IMPORTANT: The PEAR modules must be in the include path |
| 13 | * for this class to work. |
| 14 | * |
| 15 | * An array with the following elements must be passed to |
| 16 | * the class constructor (elements marked ? are optional): |
| 17 | * |
| 18 | * dsn => database DNS (see PEAR for syntax) |
| 19 | * table => table to store addresses in (must exist) |
| 20 | * owner => current user (owner of address data) |
| 21 | * ? writeable => set writeable flag (true/false) |
| 22 | * |
| 23 | * The table used should have the following columns: |
| 24 | * owner, nickname, firstname, lastname, email, label |
| 25 | * The pair (owner,nickname) should be unique (primary key). |
| 26 | * |
| 27 | * NOTE. This class should not be used directly. Use the |
| 28 | * "AddressBook" class instead. |
