1. Zend
Database
Buzoo PHP Lecture
By : Tya Herlina

2. Definition
Zend_Db and its related classes provide a
simple SQL database interface for Zend
Framework.

3. Zend_Db_Adapter
Zend_Db_Adapter is the basic class you use
to connect your PHP application to
an RDBMS. There is a different Adapter class
for each brand of RDBMS.

4. Zend_Db_Adapter (cont’d)
RDBMS
Adapter
IBM DB2
Pdo_ibm
MariaDB
Pdo_mysql
MySQL
Pdo_mysql
Microsoft SQL Server
Pdo_dblib
Oracle
Pdo_oci
PostgreSQL
Pdo_pgsql
SQLite
Pdo_sqlite

5. Set Connection
1.
2.
3.
Using a Zend_Db Adapter Constructor
Using the Zend_Db Factory
Using Zend_Config with the Zend_Db
Factory

6. 1. Using a Zend_Db Adapter
Constructor
$db = new Zend_Db_Adapter_Pdo_Mysql(array(
’host’
=> ’buzoo.biz’,
’username’ => ’root’,
’password’ => ’’,
’dbname’
=> ’app_geshucloud’
));

7. 2. Using the Zend_Db Factory
$db = Zend_Db::factory('Pdo_Mysql', array(
’host’
=> ’buzoo.biz’,
’username’ => ’root’,
’password’ => ’’,
’dbname’
=> ’app_geshucloud’
));

8. 3. Using Zend_Config with the
Zend_Db Factory
database.host
database.username
database.password
database.dbname
=
=
=
=
“buzoo.biz“
“root“
“
“app_geshucloud“
$config = new Zend_Config_Ini(“path/to/config.ini“);
$db = Zend_Db::factory(‘Pdo_Mysql‘, $config->database);

9. Set Connection
Zend_Db_Table_Abstract::setDefaultAdapter
($db);
Get Connection
public function db() {
return Zend_Db_Table_Abstract::getDefaultAdapter();
}

10. Reading Query Results

Fetching a Complete Result Set
Fetching a Single Row from a Result Set
Fetching a Single Scalar from a Result Set
Fetching a Result Set as an Associative
Array
Fetching Key-Value Pairs from a Result
Set
Fetching a Single Column from a Result
Set

11. 1. Fetching a Complete Result
Set
$models = $this->db()->fetchAll(
“SELECT * FROM `dtb_customer`”
);
print_r($models);
echo $models[0][`customerID`]; //44
Array (
[0] => Array (
[customerID]
[customerName]
[customerAddr]
[customerPhone]
[create_date]
[update_date]

)
[1] => Array (
)
)

12. 2. Fetching a Single Row from
a Result Set
$models = $this->db()->fetchRow(
“SELECT * FROM `dtb_customer` LIMIT 1”
);
print_r($models);
echo $models[`customerID`]; //44
Array (
[customerID]
[customerName]
[customerAddr]
[customerPhone]
[create_date]
[update_date]
)

13. 3. Fetching a Single Scalar
from a Result Set
$models = $this->db()->fetchOne(
“SELECT `customerID` FROM `dtb_customer` LIMIT 1”
);
print_r($models);
echo $models[`customerID`];
44

14. Modifying Data to the
Database
1.
2.
3.
Inserting Data
Updating Data
Deleting Data

15. 1. Inserting Data
$this->db()->insert(‘dtb_room_facility‘, array(
‘room_id‘
=> 99,
‘facility_id‘ => 99
));
echo $this->db()->lastInsertId(); //5
$model = new Dao_RoomFacility();
$new_id = $model->insert(array(
‘room_id‘
=> 99,
‘facility_id‘
=> 99
));
echo $new_id; //5

16. 2. Updating Data
$update_id = $this->db()->update('dtb_room_facility',
array(
'room_id'
=> 999,
'facility_id' => 999
), 'id = 999');
echo $update_id; //1
$model = new Dao_RoomFacility();
$update_id = $model->update(
array(
'room_id'
=> 899,
'facility_id' => 899
), 'id = 899');
echo $update_id; //1

17. 3. Deleting Data
$delete_id = $this->db()->delete(
'`dtb_room_facility`',
'`id` = 999'
);
echo $delete_id; //1
$model = new Dao_RoomFacility();
$delete_id = $model->delete(
'`id` = 899');
echo $delete_id; //1

18. Preventing SQL Injection
$name = "O'Reilly";
$sql =
"SELECT * FROM `dtb_customer` WHERE
`customerName` = '$name'";
echo $sql;
// SELECT * FROM `dtb_customer` WHERE `customerName`
= 'O'Reilly'

19. Quoting Values and Identifiers
1.
2.
3.
Using quote()
Using quoteInto()
Using quoteIdentifier()

20. 1. Using quote()
$name = $this->db()->quote("O'Reilly");
$sql =
"SELECT * FROM `dtb_customer` WHERE `customerName` =
$name";
echo $sql;
// SELECT * FROM `dtb_customer` WHERE `customerName` = 'O'Reilly'
$phone = $this->db()->quote("1234", "INTEGER");
$sql =
"SELECT * FROM `dtb_customer` WHERE
`customerPhone` = $phone";
echo $sql;
// SELECT * FROM `dtb_customer` WHERE `customerPhone` = 1234

21. 2. Using quoteInto()
$name = "O'Reilly";
$sql = $this->db()->quoteInto(
"SELECT * FROM `dtb_customer`
WHERE `customerName` = ?", $name
);
echo $sql;
// SELECT * FROM `dtb_customer` WHERE `customerName` = 'O'Reilly'

22. Notes
 Always
store your logic query in
Models/Logic/your_logic.php
 Minimizing the possibility of SQL injection
with quoting values
 When creating logic, please reduce the
possibility of errors
 Always return your logic result value
 Always check the existing logic before
you make yours
