CodeIgniter Database

Use the Database Library separately from CodeIgniter 3.

Installation

With Composer

"require": {
    "astute/CodeIgniterDB": "^1.0"
}

or with command line : composer require astute/CodeIgniterDB

Without Composer

You can also download it from Github, but no autoloader is provided so you'll need to register it with your own PSR-0 compatible autoloader.

Usage

<?php
use astute\CodeIgniterDB as CI;
$db_data = array(
	'dsn'	=> '',
	'hostname' => 'localhost',
	'username' => 'my_name',
	'password' => 'my_password',
	'database' => 'my_database',
	'dbdriver' => 'mysqli',
	'dbprefix' => '',
	'pconnect' => FALSE,
	'db_debug' => TRUE,
	'cache_on' => FALSE,
	'cachedir' => '',
	'char_set' => 'utf8',
	'dbcollat' => 'utf8_general_ci',
	'swap_pre' => '',
	'encrypt' => FALSE,
	'compress' => FALSE,
	'stricton' => FALSE,
	'failover' => array(),
	'save_queries' => TRUE
);
$oDb =& CI\DB($db_data);

Custom option

I've added the possibility to give a mysql ressource to reuse a already opened connection. Thus to not multiply connections and to use this in parallel with legacy code and proceed to a migration step by step. Works only with the mysql driver ! Method 1 (Direct call)

<?php
use astute\CodeIgniterDB as CI;

$db_data = array(
	'dsn'	=> '',
	'hostname' => 'localhost',
	'username' => 'root',
	'password' => 'my_name',
	'database' => 'my_database',
	'dbdriver' => 'mysql',
	'dbprefix' => '',
	'pconnect' => FALSE,
	'db_debug' => TRUE,
	'cache_on' => FALSE,
	'cachedir' => '',
	'char_set' => 'utf8',
	'dbcollat' => 'utf8_general_ci',
	'swap_pre' => '',
	'encrypt' => FALSE,
	'compress' => FALSE,
	'stricton' => FALSE,
	'failover' => array(),
	'save_queries' => TRUE
);

$rDb = mysql_connect($db_data['hostname'], $db_data['root'], $db_data['password']);

$oDb =& CI\DB($db_data, null, $rDb);

Method 2 (Config file to call the object only) Config.php

<?php 
include('src/DB.php');
use astute\CodeIgniterDB as CI;
$db_data = array(
	'dsn'	=> '',
	'hostname' => 'localhost',
	'username' => 'my_name',
	'password' => 'my_password',
	'database' => 'my_database',
	'dbdriver' => 'mysqli',
	'dbprefix' => '',
	'pconnect' => FALSE,
	'db_debug' => TRUE,
	'cache_on' => FALSE,
	'cachedir' => '',
	'char_set' => 'utf8',
	'dbcollat' => 'utf8_general_ci',
	'swap_pre' => '',
	'encrypt' => FALSE,
	'compress' => FALSE,
	'stricton' => FALSE,
	'failover' => array(),
	'save_queries' => TRUE
);
$db =& CI\DB($db_data);

index.php Calling the database object by config.php file

<?php
include('config.php');
$result1 = $db->get('table_name')->row();

$result2 = $db->select('columName')->get('table_name')->row();.

$result3 = $db->select('columName')->where('columName',1)->get('table_name')->row();
print_r($result1);
echo '<br>';
print_r($result2);
echo '<br>';
print_r($result3);
