Listing 16-1. Configuration Using an Array in the Bootstrap File (in index.php)
$configArray = (
'domain' => 'some.com',
'database' => array(
'name' => 'dbname',
'password' => 'password'
)
);
$config = new Zend_Config($configArray);
echo $config->database->name;
dbname

The INI Approach

The main difference between the INI approach and the array approach is that INI files may

define override data, which is designed to be used under certain specific circumstances, such

as when running from a staging or production server. This gives some useful flexibility, but

alone would lead to cumbersome duplication; thus, the Zend Framework INI formats allow for

sectional extension as well. Listing 16-2 shows an INI file that contains both production and

staging configuration data.

Listing 16-2. Configuration Using an INI File (Config.INI)

[production]

domain = some.com

database.name = dbname

database.password = password

[staging : production]

domain = beta.some.com

database.name = stagingdb

In this example, staging extends from production and overrides two keys, but leaves a

third password intact.

To tell Zend_Config which settings to use, the Zend_Config_Ini class is instantiated as follows:

$config = new Zend_Config_Ini('config.ini','staging');

echo $config->database->password;

password
