this is my config.ini

[general]
db.adapter = PDO_MYSQL
db.params.host = 192.168.0.233
db.params.username = root
db.params.password = my_password
db.params.dbname = "mydatabasename"

some code from my index.php

$config = new Zend_Config_Ini(ROOT_DIR.'/application/config.ini', 'general');
$DB = Zend_Db::factory($config->db);
Zend_Db_Table::setDefaultAdapter($DB);

Answer 1

it seems that your code this portion is not working

[general]
 db.adapter = PDO_MYSQL
 db.params.host = 192.168.0.233
 db.params.username = root
 db.params.password = my_password
 db.params.dbname = "mydatabasename"

either the IP is not correct if so go to cmd in windows and type ipconfig you will get your correct ip paste it here OR just simply write

 db.params.host = localhost

if and only if you are using locally may be it works.
