Zend Framework Tutorial Zend_config_ini usage Analysis _php instance

This example describes the Zend_config_ini usage of the Zend Framework tutorial. Share to everyone for your reference, as follows:

Zend_config_ini allows developers to store and read configuration data in the application using the familiar INI format through nested object property syntax. The INI format has expertise in providing the ability to inherit between hierarchy and configuration data sections that have configuration data keys. Configure data hierarchy by using dots or periods (.) Detaches the key value. A section can be extended or inherited from another section by taking a colon (:) and the name of the section that inherits the configuration data after the name of the section.

Parse_ini_file

Zend_config_ini uses the parse_ini_file () PHP function. Please review this document to learn about its specific behavior, which is used in Zend_config_ini, such as true, false, yes, no, and null for how these special values operate.

Key separators

By default, the key separator character is a period (.). However, this can be modified by modifying $options key ' Nestseparator ' when constructing the Zend_config_ini object. For example:

$options [' nestseparator '] = ': '; $config = new Zend_config_ini ('/path/to/config.ini ',               ' staging ',               $options);

Example: Using Zend_config_ini

This example illustrates the basic use of Zend_config_ini to load configuration data from an INI file.

In this example, there are configuration data for the production system (production systems) and the development system (staging systems).

Since the development of the system configuration data is similar to the configuration data of the production system, the section of the development system inherits from the section of the production system.

In this case, the result (decision) is arbitrary and it can be reversed, that is, the production system section inherits from the development system section, although this cannot be used in more complex situations.

Next, assume that the following configuration data is included in the/path/to/config.ini:

Production Site configuration data

[production]webhost =         Www.example.comdatabase.adapter     = pdo_mysqldatabase.params.host   = Db.example.comdatabase.params.username = Dbuserdatabase.params.password = Secretdatabase.params.dbname  = dbname

Develop site configuration data from the production site configuration data integration and can be overridden if necessary

[Staging:production]database.params.host   = Dev.example.comdatabase.params.username = Devuserdatabase.params.password = Devsecret

Next, assume that the developer needs to take the development configuration data from the INI file. This is very simple, as long as you specify the INI file and the development system section to load the data:

$config = new Zend_config_ini ('/path/to/config.ini ', ' staging '); Echo $config->database->params->host;  Output "dev.example.com" echo $config->database->params->dbname; Output "dbname"
