请你帮帮我。

【问题讨论】：

您可能正试图在当前版本的 PHP 上运行过时的代码。

据此：php.net/manual/en/function.mysql-pconnect.php，“mysql_pconnect() 此扩展在 PHP 5.5.0 中已弃用”。使用mysqli 或pdo

【参考方案1】：

我认为你正在使用 Codeigniter，这个错误很可能是使用了他们的数据库类和驱动程序，所以你没有直接使用 PHP 的 MySQL 函数。

因此，你需要做的就是改变

$db['default']['dbdriver'] = 'mysql';

到

$db['default']['dbdriver'] = 'mysqli';

为您的 database.php 文件添加以下设置

$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
);

很好地了解CI_ 课程 ;)

是的，注意到CI_DB_driver ;)

好的，我正在使用此代码，但问题仍然存在：$db['default']['hostname'] = 'localhost'; $db['default']['username'] = 'root'; $db['default']['password'] = ''; $db['default']['database'] = '拼车'; $db['default']['dbdriver'] = 'mysqli'; $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'] = '';

更新我的答案以获得额外的价值。

感谢最终代码：$active_group = 'default'; $active_record = TRUE; $db['default'] = array('dsn' => '', 'hostname' => 'localhost', 'username' => 'root', 'password' => '', 'database' => ' carpooling', '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, '故障转移' => array(), 'save_queries' => TRUE );这是正确的？出现同样的错误
