require_once 'DB.php'; require_once 'DataObjects/Person.php'; $person = new Person(); $person->id = 1; $result = $person->dbdelete(); if (PEAR::isError($result)) { echo "Error deleting person: " . $result->getMessage(); } else { echo "Person deleted successfully"; }
require_once 'DB.php'; require_once 'DataObjects/Book.php'; $books = Book::all(); foreach ($books as $book) { if ($book->author == 'J.K. Rowling') { $book->dbdelete(); } } echo "J.K. Rowling's books deleted successfully";In this example, we are using the dbdelete method to delete all books written by J.K. Rowling from the Book table. We first fetch all books using the Book::all() method, then loop through them and check if the author is J.K. Rowling. If it is, we delete the book using the dbdelete method. The result of the operation is not checked as we assume that all deletions will be successful. The package library used in these examples is PEAR DB, which provides a database abstraction layer on top of PHP's native database functions. The DataObject library is also used, which is a simple and flexible ORM (Object-Relational Mapping) tool that provides a consistent API for database manipulation.
