Introduction:
This blog is about zend 2 framework,and not good. because is have so hard to read.
Contain:
- mysql profile.
- mvc
- no view render
- json output
- gzip compress
- view helper
1.db profile (mysql)
1.1 db profile
1.1.1 config/autoload/local.php
(description:this is local private profile file.)
<?php

* .dist extension at the end and populate values as needed.
*
* @NOTE: This file is ignored from Git by default with the .gitignore included
* in ZendSkeletonApplication. This is a good practice, as it prevents sensitive
* credentials from accidentally being committed into version control.

1.1.2 config/autoload/global.php
(description:this is global profile file.)
<?php

1.2 model
data table is “Keyword”:
CREATE TABLE `pkrss_rsskeyword` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`key` varchar(32) NOT NULL,
`count` int(11) NOT NULL,
`type` char(4) NOT NULL DEFAULT 'r' COMMENT 'r:rss b:bookimage',
PRIMARY KEY (`id`),
UNIQUE KEY `key` (`key`,`type`)
) ENGINE=MyISAM AUTO_INCREMENT=1 DEFAULT CHARSET=utf8
and i used in module name “api”.
1.3 Module/Api/src/Api/Model/Keyword.php
