嗯.在Windows 8上尝试执行此操作似乎会产生与您指定的错误相同的错误.我目前正在调查...

我的错误(我启用了错误的extension_dir行).如下所述，它可以在Win8中工作.

My mistake (I had enabled the wrong extension_dir line). It works in Win8 just as documented below.

以下步骤应是使OCI与PHP一起工作所需的全部(我刚刚在新安装的Windows 2008 R2 Standard x64虚拟机上对此进行了验证):

The following steps should be all you need to get OCI working with PHP (I've just verified this on a freshly installed Windows 2008 R2 Standard x64 virtual machine):

• 下载并解压缩PHP(我从php-5.6.7-nts-Win32-VC11-x86.zip中使用C:\php).
• 下载并解压缩InstantClient(我从instantclient-basic-nt-12.1.0.2.0.zip使用C:\instantclient_12_1).
• 将上述路径添加到系统路径.
• 将c:\php\php.ini-production复制到c:\php\php.ini.
中的
• :
  • 启用了行extension_dir = "ext".
  • 启用了行extension=php_oci8_12c.dll.
  • Download and extract PHP (I used C:\php from php-5.6.7-nts-Win32-VC11-x86.zip).
  • Download and extract InstantClient (I used C:\instantclient_12_1 from instantclient-basic-nt-12.1.0.2.0.zip).
  • Add the above paths to the system path.
  • Copy c:\php\php.ini-production to c:\php\php.ini.
  • in php.ini:
    • enabled line extension_dir = "ext".
    • enabled line extension=php_oci8_12c.dll.

    这时在命令提示符下运行php --ri oci8会显示以下输出:

    At this point running php --ri oci8 in a command prompt shows me the following output:

    C:\>php --ri oci8

    OCI8 Support => enabled
    OCI8 DTrace Support => disabled

    并检查oci_connect功能:

    C:\>php -r "var_dump(function_exists('oci_connect'));"
    bool(true)
