在UCenter_1.6.0_SC_UTF8下启用MySQL增强版扩展，即Mysqli扩展

1、复制Discuz_X3.2_SC_UTF8/upload/uc_server/lib/dbi.class.php到UCenter_1.6.0_SC_UTF8/lib/dbi.class.php

2、编辑UCenter_1.6.0_SC_UTF8/model/base.php

function init_db() {
//require_once UC_ROOT.’lib/db.class.php’;
if(function_exists(“mysqli_connect”)) {
require_once UC_ROOT.’lib/dbi.class.php’;
} else {
require_once UC_ROOT.’lib/db.class.php’;
}
$this->db = new ucserver_db();
$this->db->connect(UC_DBHOST, UC_DBUSER, UC_DBPW, UC_DBNAME, UC_DBCHARSET, UC_DBCONNECT, UC_DBTABLEPRE);
}

3、复制Discuz_X3.2_SC_UTF8/upload/uc_server/api/dbbak.php的class dbstuffi至UCenter_1.6.0_SC_UTF8/api/dbbak.php中

4、编辑UCenter_1.6.0_SC_UTF8/api/dbbak.php

5、在uc_client中启用Mysqli扩展，复制Discuz_X3.2_SC_UTF8/upload/uc_client/lib/dbi.class.php到uc_client/lib/dbi.class.php

6、编辑uc_client/client.php，

if(empty($uc_controls[$model])) {
//include_once UC_ROOT.’./lib/db.class.php’;
if(function_exists(“mysqli_connect”)) {
include_once UC_ROOT.’./lib/dbi.class.php’;
} else {
include_once UC_ROOT.’./lib/db.class.php’;
}
include_once UC_ROOT.’./model/uc_base.php’;
include_once UC_ROOT.”./control/$model.php”;
eval(“\$uc_controls[‘$model’] = new {$model}control();”);
}

7、编辑/uc_client/model/uc_base.php

function init_db() {
//require_once UC_ROOT.’lib/db.class.php’;
if(function_exists(“mysqli_connect”)) {
require_once UC_ROOT.’lib/dbi.class.php’;
} else {
require_once UC_ROOT.’lib/db.class.php’;
}
$this->db = new ucclient_db();
$this->db->connect(UC_DBHOST, UC_DBUSER, UC_DBPW, ”, UC_DBCHARSET, UC_DBCONNECT, UC_DBTABLEPRE);
}
