PHP配置问题(mysql_connect)报错_course

之前因为比较懒，就装了PHPnow,PHP版本是5.2,最近因为要学thinkPHP框架，由于用的是thinkPHP3.2，需要PHP5.3以上版本才能跑起来，就手动更新了PHP版本，更新到了5.3.5，并按照正常步骤配置了php.ini文件，打开了(extension_dir = "\ext" extension=php_mysql.dll; extension=php_mysqli.dll;)等模块，重启Apache，运行了一下之前写的练手项目，但只要和数据库连接有关的，都报了如下这个错误（Fatal error: Call to undefined function mysql_connect() in E:\php\htdocs\wangshangshudian\login.php on line 7），但是我都把php.ini相应和MySQL有关的模块都打开了，怎么还是这个问题呢，我就郁闷了，望各位大神帮忙看下是哪出错了，并且thinkPHP也出现了如下错误：:( 系统不支持:mysql 错误位置 FILE: E:\php\htdocs\demo\ThinkPHP\Library\Think\Db\Driver\Mysql.class.php 　LINE: 27 TRACE #0 E:\php\htdocs\demo\ThinkPHP\Library\Think\Db\Driver\Mysql.class.php(27): E('???????????????...') #1 E:\php\htdocs\demo\ThinkPHP\Library\Think\Db.class.php(90): Think\Db\Driver\Mysql->__construct(Array) #2 E:\php\htdocs\demo\ThinkPHP\Library\Think\Db.class.php(65): Think\Db->factory('') #3 E:\php\htdocs\demo\ThinkPHP\Library\Think\Model.class.php(1287): Think\Db::getInstance('') #4 E:\php\htdocs\demo\ThinkPHP\Library\Think\Model.class.php(95): Think\Model->db(0, '', true) #5 E:\php\htdocs\demo\ThinkPHP\Common\functions.php(554): Think\Model->__construct('user', '', '') #6 E:\php\htdocs\demo\Application\Home\Controller\DBController.class.php(6): M('user') #7 [internal function]: Home\Controller\DBController->index() #8 E:\php\htdocs\demo\ThinkPHP\Library\Think\App.class.php(155): ReflectionMethod->invoke(Object(Home\Controller\DBController)) #9 E:\php\htdocs\demo\ThinkPHP\Library\Think\App.class.php(193): Think\App::exec() #10 E:\php\htdocs\demo\ThinkPHP\Library\Think\Think.class.php(120): Think\App::run() #11 E:\php\htdocs\demo\ThinkPHP\ThinkPHP.php(96): Think\Think::start() #12 E:\php\htdocs\demo\index.php(24): require('E:\php\htdocs\d...') #13 {main}
