connect_error) { die("Connection failed: " . $conn->connect_error); } // Delete all records from the table $sql = "DELETE FROM users"; if ($conn->query($sql) === TRUE) { echo "All records deleted successfully!"; } else { echo "Error deleting records: " . $conn->error; } // Close connection $conn->close(); ?>In the code above, we establish a connection to the database, and then execute an SQL statement to delete all records from the "users" table. Finally, we close the connection to the database. The "deleteAll" method is a part of the database package/library in PHP, which is used to interact with databases. PHP provides several database extensions such as mysqli, PDO, and etc. that can be used to connect with various databases.
