服务器/本地主机之间的不同环境正在更改日期格式-PHP PDO MySQL / oci

Question

I'm having problems to configure my server environment, the PHP with PDO is not formatting the date like the localhost. 我在配置服务器环境时遇到问题，带有PDO的PHP无法像本地主机一样格式化日期。 To test it, I created two connections (using pdo with oci and mysql). 为了测试它，我创建了两个连接（在oci和mysql中使用pdo）。 On localhost, oci and mysql runs normally, but on server only the mysql maintains the correct format. 在localhost上，oci和mysql正常运行，但在服务器上只有mysql保持正确的格式。

IMPORTANT DETAIL: On sqldeveloper, it shows the data in the same format like localhost pdo/oci. 重要说明：在sqldeveloper上，它以与localhost pdo / oci类似的格式显示数据。

MY LOCALHOST IS WINDOWS 7 AND MY SERVER IS LINUX DEBIAN X64. 我的本地主机是WINDOWS 7，我的服务器是LINUX DEBIAN X64。

What could to be happening with pdo/oci on server? 服务器上的pdo / oci会发生什么？

In Oracle, you can use the following to change the default format used for date conversion to match the MySQL default: 在Oracle中，可以使用以下命令更改用于日期转换的默认格式以匹配MySQL的默认格式：

ALTER SESSION SET NLS_DATE_FORMAT='yyyy-mm-dd hh24:mi:ss';

This will make the Oracle dates output like MySQL dates always do. 这将使Oracle日期输出始终像MySQL日期一样。

You can make this happen on every connect with PDO: 您可以在每次使用PDO进行连接时使这种情况发生：

$driver_options = array( PDO::MYSQL_ATTR_INIT_COMMAND => 'ALTER SESSION...' );
try {
    $dbh = new PDO($dsn, $user, $pw, $driver_options);
}
catch (PDOException $e) {
    // Handle exception
}

Both Oracle and MySQL also have functions to format dates explicitly, which you can call in expressions in your query select-list. Oracle和MySQL都具有显式格式化日期的功能，您可以在查询选择列表中调用表达式。 But in Oracle the function is TO_CHAR() and in MySQL the function is DATE_FORMAT(), which makes it harder to write RDBMS-independent code. 但是在Oracle中，函数是TO_CHAR（），在MySQL中，函数是DATE_FORMAT（），这使得编写与RDBMS无关的代码变得更加困难。

Re your comment: 发表您的评论：

It seems the NLS_DATE_FORMAT can be set globally in initORCL.ora , it can be set by a LOGON trigger, it can be set at the session level, etc. This could account for the different behavior in two different environments. 看来NLS_DATE_FORMAT可以在initORCL.ora全局设置，可以通过LOGON触发器设置，可以在会话级别设置，等等。这可以解释两种不同环境中的不同行为。 Here's an interesting post about it: 这是一篇有趣的文章：
