phpmyadmin是个很方便的mysql数据库管理工具,可以用来管理mysql数据库,导入,导出等。

phpmyadmin在导入mysql的时候有个问题,如果要导入的数据库文件比较大,那么导入就会失败。下面介绍一个方法,可以导入任意大小的mysql数据库,步骤如下:

1. 通过FTP把数据库的SQL文件上传到网站的根目录下
2. 在网站的根目录下,创建文件import.php,该文件的内容见文章末尾
3. 在浏览器里面访问这个import.php,假设你的网站域名是www.a.com,那么就在浏览器里面访问 http://www.a.com/import.php , 只要浏览器一开始访问这个import.php文件,数据就开始导入了
4. 数据导入结束后,屏幕上会出现”import ok”的字样

import.php文件的内容如下:

< ?
system("mysql -uroot -pmypassword database < a.sql");
print "import ok";
?>

其中root表示数据库用户名,mypassword表示root的密码,database表示要导入的数据库的名字,a.sql表示数据库文件的文件名,该文件是解压缩后的文件。这几个变量可以根据实际情况修改。

In PHP 4.2.0 and later, the default value for the PHP directive register_globals is off. This is a major change in PHP. Having register_globals off affects the set of predefined variables available in the global scope. For example, to get DOCUMENT_ROOT you’ll use $_SERVER['DOCUMENT_ROOT'] instead of $DOCUMENT_ROOT, or $_GET['id'] from the URL http://www.example.com/test.php?id=3 instead of $id, or $_ENV['HOME'] instead of $HOME.

For related information on this change, read the configuration entry for register_globals, the security chapter on Using Register Globals , as well as the PHP » 4.1.0 and » 4.2.0 Release Announcements.

Using the available PHP Reserved Predefined Variables, like the superglobal arrays, is preferred [...]
