提问by Awan
As you may have known that I switched from ubuntu to windows from my previous questions. I was working on Zend Framework on ubuntu and now working on same project in windows. Because of this switching I am facing some problems in windows which was not occurred in ubuntu.
您可能已经知道，我从之前的问题中从 ubuntu 切换到了 Windows。我在 ubuntu 上开发 Zend Framework，现在在 Windows 上开发同一个项目。由于这种切换，我在 windows 中遇到了一些在 ubuntu 中没有发生的问题。
Now I have the following error in firebug console when I go to login page:
现在，当我进入登录页面时，firebug 控制台中出现以下错误：
<b>Fatal error</b>: Undefined class constant 'MYSQL_ATTR_INIT_COMMAND' in <b>C:\wamp\www\vcred\library\Zend\Db\Adapter\Pdo\Mysql.php</b> on line <b>93</b><br />
Do you people know that what type of error is this and what is the solution?
你们知道这是什么类型的错误以及解决方案是什么？
I have the following configuration for database.
我有以下数据库配置。
resources.db.adapter = "Pdo_Mysql"
resources.db.params.host = "localhost"
resources.db.params.username = "root"
resources.db.params.password = ""
resources.db.params.dbname = "test"
resources.db.params.charset = "utf8"

This looks related to this bug on PHP's bugtracker : Bug #47224 MYSQL_ATTR_INIT_COMMANDis no longer available
这看起来与 PHP 的 bugtracker 上的这个 bug 有关：Bug #47224MYSQL_ATTR_INIT_COMMAND不再可用
It seems it's been fixed in SVN -- but maybe not in the version of PHP you are using ?
似乎它已在 SVN 中修复——但可能不是在您使用的 PHP 版本中？
Quoting one of the comments :
引用其中一条评论：

A temporary solution is to use INT value (1002) instead of constant.

一个临时解决方案是使用 INT 值 (1002) 而不是常数。
This might be a temporary solution, until you install a new version of PHP, in which the bug is fixed ?
这可能是一个临时解决方案，直到您安装新版本的 PHP，其中修复了错误？

I just had the same error with PHP 5.2.6, and all I had to do is to open php.ini(e.g. on Windows: C:\Windows\php.ini, or on Ubuntu: /etc/php5/apache2/php.inior sg. like this) in a text editor, and remove the semicolon from the following line:
我只是在 PHP 5.2.6 上遇到了同样的错误，我所要做的就是打开php.ini（例如在 Windows 上：C:\Windows\php.ini，或在 Ubuntu 上：/etc/php5/apache2/php.ini或sg。像这样）在文本编辑器中，并从以下行中删除分号：
;extension=php_pdo_mysql.dll
So as a result it would look like this in php.ini:
因此，它在 php.ini 中看起来像这样：
extension=php_pdo_mysql.dll
That solved my problem.
那解决了我的问题。

Looks like a Windows bug in PHP 5.3that was fixed in SVN a while ago. You might want to try updating to the latest PHP release to see if the issue still exists.
看起来像PHP 5.3中的一个Windows 错误，它在不久前在 SVN 中得到了修复。您可能想尝试更新到最新的 PHP 版本以查看问题是否仍然存在。

I got the same error, on debian6, when I had not yet installed php-mysqlso, I simply installed this, like this
我遇到了同样的错误，在 debian6 上，当我还没有安装时php-mysql，我只是安装了这个，就像这样
apt-get install php5-mysql
/etc/init.d/apache2 restart
I just add it here, in case other have same problem, to save them them a few minutes of research.
我只是在这里添加它，以防其他人有同样的问题，为他们节省几分钟的研究时间。
