This article will explain in detail how to achieve database connection, configuration and use of CodeIgniter. The editor thinks it is very practical, so I share it with you as a reference. I hope you can get something after reading this article.

The details are as follows:

1. Database:

Create database test;create table users (id int not null,name varchar (10), pwd varchar (10), email varchar (20)) insert into users values (1recorder shunpingjinjiao shunpingzhongjinshunpingjinjiaaqing163.com'); insert into users values (2mianshunping2jingshunping2fujingshunping2jinshunping2jinshunping2jinshunping2shunping2shunping2shunping2shunping2shunping2shunping2com')

two。 I use Postgreql.

Configure the database parameters in the\ CodeIgniter\ system\ application\ config\ database.php file:

$active_group = "default"; $db ['default'] [' hostname'] = "localhost"; $db ['default'] [' username'] = "postgres"; $db ['default'] [' password'] = "admin"; $db ['default'] [' database'] = "test"; $db ['default'] [' dbdriver'] = "postgre"; $db ['default'] [' dbprefix'] = "; $db ['default'] [' active_r'] = TRUE $db ['default'] [' pconnect'] = FALSE;$db ['default'] [' db_debug'] = TRUE;$db ['default'] [' cache_on'] = FALSE;$db ['default'] [' cachedir'] = ""; $db ['default'] [' port'] = "5432"

Test the file db1.php in the\ CodeIgniter\ system\ application\ controllers directory as follows:

Open the browser and type in the address:

Http://localhost:8888/index.php/MyController/db1

Ok, get it!
