Codeigniter 错误:调用未定义的函数 mysql_pconnect() [英] Codeigniter error: Call to undefined function mysql_pconnect()

问题描述

我已将我的 codeigniter 版本从 2.2.4 逐步更新到 3.0.6，但出现错误:

I have updated my codeigniter version from 2.2.4 step by step to 3.0.6 and I get an error:

An uncaught Exception was encountered

Type: Error

Message: Call to undefined function mysql_pconnect()

Filename: path-to-projectsystemdatabasedriversmysqlmysql_driver.php

Line Number: 135

Backtrace:

File: path-to-projectapplicationcontrollersMain.php
Line: 10
Function: __construct

File: path-to-projectindex.php
Line: 315
Function: require_once

我刚刚用新的替换了我的 index.php 文件和系统目录，并根据教程对我的应用程序进行了一些更改.

I have just replaced my index.php file and system directory with the new one and made some changes in my application according to tutorial.

这是主控制器:

class Main extends CI_Controller {

    function __construct()
    {
        parent::__construct();
        $this->load->model('main_model');
    }
}

导致问题的原因是什么?！

What causes the problem?!

还有这是教程的链接.

推荐答案

我得出一个结论:

我用新的文件完全改变了我在 config 文件夹中的旧 database.php 文件:

I completely changed my old database.php file in config folder with the new one:

来自:

$db['default']['hostname'] = 'localhost';
$db['default']['username'] = '';
$db['default']['password'] = '';
$db['default']['database'] = '';
$db['default']['dbdriver'] = '';
$db['default']['dbprefix'] = '';
$db['default']['pconnect'] = TRUE;
$db['default']['db_debug'] = TRUE;
$db['default']['cache_on'] = FALSE;
$db['default']['cachedir'] = '';
$db['default']['char_set'] = 'utf8';
$db['default']['dbcollat'] = 'utf8_general_ci';
$db['default']['swap_pre'] = '';
$db['default']['autoinit'] = TRUE;
$db['default']['stricton'] = FALSE;

致:

$db['default'] = array(
    'dsn'   => '',
    'hostname' => '',
    'username' => '',
    'password' => '',
    'database' => '',
    'dbdriver' => 'mysqli',
    'dbprefix' => '',
    '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
);

错误消失了！
