php.ini：
extension_dir = c:/phpenv/php-5.2/ext
extension=php_mysql.dll
extension=php_mysqli.dll
extension=php_bz2.dll
extension=php_gd2.dll
php文件：
apache error.log:
php fatal error: call to undefined function mysql_connect() in c:\\phpenv\\apache2.2\\htdocs\\testmysql.php on line 2
请问是怎么回事啊？
------解决方案--------------------
phpinfo();
检查php.ini 路径是否是修改过的文件.
