codeigniter set db prefix

Step 1: Open the CodeIgniter configuration file located at application/config/database.php.

Step 2: Locate the 'dbprefix' configuration setting within the $db array.

Step 3: Set the 'dbprefix' value to the desired database table prefix.

Step 4: Save the changes to the configuration file.

Example:

// application/config/database.php

$db['default'] = array(
    'dsn'   => '',
    'hostname' => 'localhost',
    'username' => 'your_username',
    'password' => 'your_password',
    'database' => 'your_database',
    'dbdriver' => 'mysqli',
    'dbprefix' => 'your_prefix_',  // Set your desired database table prefix
    'pconnect' => FALSE,
    'db_debug' => (ENVIRONMENT !== 'production'),
    'cache_on' => FALSE,
    'cachedir' => '',
    'char_set' => 'utf8',
    'dbcollat' => 'utf8_general_ci',
    'swap_pre' => '',
    'encrypt' => FALSE,
    'compress' => FALSE,
    'stricton' => FALSE,
    'failover' => array(),
    'save_queries' => TRUE
);

Replace 'your_prefix_' with the desired prefix for your database tables. Save the changes to the file.
