在wamp中为PHP启用opcache [英] Enable opcache for php in wamp

问题描述

我尝试在wamp上启用opcache，但是它不起作用.我这样更改设置:

I try to enable opcache on wamp but it doesnt work. I changed the settings like this :

[opcache]
zend_extension=C:/wamp/bin/php/php5.5.12/ext/php_opcache.dll
opcache.enable=1
opcache.enable_cli=1
opcache.memory_consumption=128
opcache.interned_strings_buffer=8
opcache.max_accelerated_files=4000

我在opcache的php扩展名中总是带有红色感叹号 怎么了?一些帮助请

推荐答案

在PHP5.5.12中，opcache作为zend扩展名提供，但可以在标准ext文件夹中找到.

In PHP5.5.12 opcache is delivered as a zend extension but it is found in the standard ext folder.

因此，除了使用zend_extension而不是extension参数之外，您将像其他任何PHP扩展一样加载它，因此请使用wampmanager菜单编辑php.ini文件，以确保像这样编辑正确的文件. :-

You would therefore load it just like any other PHP extension, apart from using the zend_extension rather than extension paramter, so edit your php.ini file using the wampmanager menus to make sure you edit the right file like so :-

wampmanager -> PHP -> php.ini

首先检查此参数的设置是否正确:

First check that this parameter is set correctly :

extension_dir = "C:/wamp/bin/php/php5.5.12/ext/"

现在在示例中已加载OpCache dll的位置，请按照以下步骤进行操作，它将从默认扩展名文件夹中加载，就像普通的extension=将是:-

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 :-

zend_extension=php_opcache.dll

您可以这样做:-

zend_extension="C:/wamp/bin/php/php5.5.12/ext/php_opcache.dll"

，但是无需指定从标准ext文件夹加载的完整路径.

but there is no need to specify the full path as it is loaded from the standard ext folder.

警告

Warning

如果您仍在开发中，几乎可以肯定不要打开它，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，在每次代码更改后检索，并且可能不会重新编译并使用不需要的时候缓存代码.

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.
