我想启用与oracle db的连接，但我所做的一切都不起作用：
我的phpinfo()没有显示oci8的单独部分，但在phpinfo开始时有
Architecture x86
Configure Command cscript /nologo configure.js "--enable-snapshot-build"
"--disable-isapi"
"--enable-debug-pack"
"--without-mssql"
"--without-pdo-mssql"
"--without-pi3web"
"--with-pdo-oci=C:\php-sdk\oracle\x86\instantclient10\sdk,shared"
"--with-oci8=C:\php-sdk\oracle\x86\instantclient10\sdk,shared"
"--with-oci8-11g=C:\php-sdk\oracle\x86\instantclient11\sdk,shared"
"--enable-object-out-dir=../obj/"
"--enable-com-dotnet=shared"
"--with-mcrypt=static"
"--disable-static-analyze"
"--with-pgo"
我已经下载了instantclient 11_2和修改后的窗口path，最后添加了C:\xampp\oracle_driver\和php.ini，如下所示：
extension=php_pdo_oci.dll
extension=php_oci8.dll
extension=php_oci8_11g.dll
