文件编写时的Ruby编码(Ruby Encoding While File Writing)

 memcached服务实际上并不为你安装PHP memcached扩展。 它只安装用于存储缓存的memcached服务器。 
 
 您需要首先从PECL存储库下载Windows DLL （ 单击蓝色的Windows DLL链接 ）。 然后，您必须将extension=php_memcache.dll行添加到SAPI的正确php.ini文件中。 另外，请注意扩展DLL文件需要放在XAMPP安装的正确路径中。 
 
 对于Apache，只需使用<?php phpinfo();在文档根目录下创建一个脚本<?php phpinfo(); 并尝试在您的网页浏览器中加载。 你应该在标有Loaded configuration（php.ini）的顶部看到一行，它给你加载php.ini文件的完整路径。 在Windows中，如果通过类似XAMPP的方式安装了PHP，路径实际上可能与phpinfo()所述的路径不同。 所以你可能需要依靠XAMPP来找到正确的php.ini文件。 
 
 对于CLI SAPI，您可以使用php.exe --ini来执行相同的操作。 同样，如果它修改了你的配置路径（ 因为这是一个编译时指令 ），你可能需要依赖XAMPP包。 
 
 在对php.ini进行更改后，您需要重新启动PHP才能使更改生效。 
 
 
 由于您在Windows上使用PHP 7，因此可能很重要的一点是，从PECL编译的DLL实际上可能不适用于Windows的apache，因为您很可能使用了领导的SAPI。 所以确保你正在下载正确的版本。 据我所知，该版本只能编译到PHP 5.6以上。 在评论中提到的https://github.com/nono303/PHP7-memcahe-dll中提供的github替代方案，可在非线程安全下进行测试。 所以你可能只能在Windows上为你的CLI脚本工作。 

The memcached service doesn't actually install the PHP memcached extension for you. It only installs the memcached server used to store your cache.
 
You'll need to download the Windows DLL from the PECL repository first (click on the blue Windows DLL link). Then you must add the extension=php_memcache.dll line to the correct php.ini file for your SAPI. Also, note the extension DLL file needs to be placed in the correct path for your XAMPP installation.
 
For Apache, simply create a script in your document root with the line <?php phpinfo(); and try loading that in your web browser. You should see a line at the top labeled Loaded configuration (php.ini) which gives you the full path to your loaded php.ini file. On Windows the path may actually appear different than what is stated in phpinfo() if you installed PHP through something like XAMPP. So you may need to rely on XAMPP to locate the correct php.ini file.
 
For the CLI SAPI, you can use php.exe --ini to do the same. Again, you may need to rely on the XAMPP package if it has modified your configuration path (since this is a compile time directive).
 
After making your changes to php.ini you will need to restart PHP for the changes to take effect.
 
 
Since you're using PHP 7 on Windows it's probably also important to note that the compiled DLL from PECL may not actually work under apache for Windows, because you're more than likely using a theaded SAPI. So make sure you are downloading the correct version. As far as I can tell that version is only compiled to work with up to PHP 5.6. The github alternative, for PHP 7, available at https://github.com/nono303/PHP7-memcahe-dll as mentioned in the comments is tested under non-thread safe. So you may only be able to get this working for your CLI scripts on Windows.
