CONFIGURAR config.inc.php

[flopezcpa]

$dbconfig['db_server'] = 'localhost';
$dbconfig['db_port'] = ':3306';
$dbconfig['db_username'] = 'root';
$dbconfig['db_password'] = '';
$dbconfig['db_name'] = 'corebos80';
$dbconfig['db_type'] = 'mysqli';
$dbconfig['db_status'] = 'true';
$dbconfig['persistent'] = false;
$dbconfig['db_hostname'] = $dbconfig['db_server'].$dbconfig['db_port'];
$host_name = $dbconfig['db_hostname'];

Es aqui donde debo cambiar los datos?

quedaria asi?

$dbconfig['db_hostname'] = $dbconfig['localhost'].$dbconfig['3306'];
$host_name = $dbconfig['db_hostname'];
