ORACLE 12c + PHP 5.6.13 (Win32) -无法加载php_pdo_oci.dll

Database-Server: ORACLE 12c

App-Server: Windows NT SERVER1 6.3 build 9200 (Windows Server 2012 R2 Standard Edition) i586

Apache:

Apache/PHP/5.6.13 2.4.16 (Win32)

PHP:

php-5.6.13-Win32-VC11-x86

使用这些组件，我尝试执行这个小php脚本，并得到这个警告:

<?php
    foreach(PDO::getAvailableDrivers() as $driver)
      {
      echo $driver.'<br />';
      }  
?>
Warning: PHP Startup: Unable to load dynamic library 'C:/Program Files (x86)/php-5.6.13-Win32-VC11-x86/ext'php_pdo_oci.dll' - %1 ist keine zulässige Win32-Anwendung.
 in Unknown on line 0

目前为止的翻译:%1是不允许的Win32-Application

问题:PHP 5.6.13 (Win32)无法加载ext/php_pdo_oci.dll库，因为"this list no Win32- application " ?

不知道怎么了
