In PHP5.5.12 opcache is delivered as a zend extension but it is found in the standard extfolder.
在 PHP5.5.12 中 opcache 是作为 Zend 扩展提供的，但它位于标准ext文件夹中。
You would therefore load it just like any other PHP extension, apart from using the zend_extensionrather than extensionparamter, so edit your php.inifile using the wampmanager menus to make sure you edit the right file like so :-
因此，除了使用zend_extension而不是extension参数之外，您可以像任何其他 PHP 扩展一样加载它，因此请php.ini使用 wampmanager 菜单编辑您的文件，以确保您像这样编辑正确的文件：-
wampmanager -> PHP -> php.ini
First check that this parameter is set correctly :
首先检查这个参数设置是否正确：
extension_dir = "C:/wamp/bin/php/php5.5.12/ext/"
Now where you have loaded the OpCache dll in your example, do it like this and it will be loaded from the default extension folder just like a normal extension=would be :-
现在你已经在你的例子中加载了 OpCache dll，这样做，它会从默认扩展文件夹中加载，就像正常情况一样extension=：-
zend_extension=php_opcache.dll
You could do it like this :-
你可以这样做：-
zend_extension="C:/wamp/bin/php/php5.5.12/ext/php_opcache.dll"
but there is no need to specify the full path as it is loaded from the standard extfolder.
但无需指定完整路径，因为它是从标准ext文件夹加载的。
Warning
警告
If you are still developing you almost definitely don't what this turned on as it won't add any benefit and could add time to a standard compilation, recaching after every code change, and possibly not re-compiling and using the cached code when you don't want it to.
如果您仍在开发中，您几乎肯定不会打开它，因为它不会增加任何好处，并且可能会增加标准编译的时间，在每次代码更改后重新缓存，并且可能不会重新编译和使用缓存的代码你不希望它。

Since you are working on windows i think you should set the path like this
由于您在 Windows 上工作，我认为您应该像这样设置路径
zend_extension=C:\path\to\php_opcache.dll (win) [Note the slash]
zend_extension=C:\path\to\php_opcache.dll (win) [注意斜线]
for your case: zend_extension=C:\wamp\bin\php\php5.5.12\ext\php_opcache.dll
对于您的情况： zend_extension=C:\wamp\bin\php\php5.5.12\ext\php_opcache.dll
Note that when the path contains spaces you should wrap it in quotes:
请注意，当路径包含空格时，您应该将其用引号括起来：
zend_extension="C:\Program Files\PHP5.5\ext\php_opcache.dll"
zend_extension="C:\Program Files\PHP5.5\ext\php_opcache.dll"
Try it out and see if it helps
试试看是否有帮助
