How do I install PDO drivers for PHP on Windows?
提问by Don Rhummy
I installed Apache, PHP 5.6 and MySQL 5.7 on a Windows server.
我在 Windows 服务器上安装了 Apache、PHP 5.6 和 MySQL 5.7。
In php.ini, I enabled the following:
在 php.ini 中，我启用了以下内容：
extension=php_mysql.dll
extension=php_mysqli.dll
extension=php_oci8_12c.dll
extension=php_pdo_mysql.dll
extension=php_pdo_oci.dll
(And restarted Apache)
（并重新启动Apache）
But when I try to use PDO in my php page, it still throws the error:
但是当我尝试在我的 php 页面中使用 PDO 时，它仍然抛出错误：
Fatal error: Uncaught exception 'PDOException' with message 'could not find driver'
What do I have to do to get PDO installed?
我需要做什么才能安装 PDO？

The problem was the extension_dirdirective did not work as a relative path. Changing from extension_dir="ext"to extension_dir="c:/phpinstall_path/ext"fixed the problem.
问题是该extension_dir指令不能用作相对路径。更改extension_dir="ext"为extension_dir="c:/phpinstall_path/ext"解决了问题。

In my apache httpd.confI have (note I have # as remmed out because it took me 1 hour at least). So I left it to show me how notto do it.
在我的 apache 中httpd.conf我有（注意我有 # as remmed，因为它至少花了我 1 小时）。所以我留下它来告诉我如何不这样做。
#PHPIniDir 'c:\apps\php\'
#PHPIniDir "C:\Apache24\~PHP_download\php-5.6.11-Win32-VC11-x64\"
PHPIniDir "C:/Apache24/~PHP_download/php-5.6.11-Win32-VC11-x64"
#LoadModule php5_module "c:/apps/php/php5apache2_2.dll"
LoadModule php5_module "C:/Apache24/~PHP_download/php-5.6.11-Win32-VC11-x64/php5apache2_4.dll"
AddHandler application/x-httpd-php .php
In the above folder (and seen below) I have these files:
在上面的文件夹中（如下所示），我有这些文件：

And in that same folder, in the php.ini file I have the following block that are pdo-related, with the ones in force not remmed out with a ;
在同一个文件夹中，在 php.ini 文件中，我有以下与 pdo 相关的块，其中有效的块没有用 ;

then I have a phpinfo_xyz.phpfilefor testing purposes only (read: delete it when you are done) that contains
那么我有一个仅用于测试目的的phpinfo_xyz.php文件（阅读：完成后删除它），其中包含

Restart apache, point to that filefrom a browser and notice the following blocks similar to the following three.
重新启动 apache，从浏览器指向该文件并注意以下与以下三个类似的块。

In the first PHP picture above from phpinfo(), it was the getting the path right in httpd.conf that took the longest. That is why I left in the wrong path attempts seen in this Answer.
在上面的第一张 PHP 图片中，phpinfo()在 httpd.conf 中获取正确路径花费的时间最长。这就是为什么我在这个答案中看到的错误路径尝试。
So it wasn't until Loaded Configuration Fileshowed up decent that it had a chance.
所以直到Loaded Configuration File出现体面的时候，它才有机会。
Good luck. It was not fun. Half the problem was there were like 2 or 4 options of which original download to perform. Sadly I think it took me 2 or 3 hours all together. But I am not as smart as the rest of you.
祝你好运。这不好玩。一半的问题是有 2 或 4 个选项可以执行原始下载。可悲的是，我认为我总共花了 2 或 3 个小时。但我没有你们其他人那么聪明。
