Install Memcached XAMPP Windows 10

Memcache is a caching system used to speed up web applications by holding small pieces of arbitrary data, it could be broadly compared to the $_SESSION variable in PHP, but memcache works across the whole application not just on a per user basis and has been successfully proven to make great gains in speed increases on web applications.

Memcache was designed with Linux in mind and not windows, so it has posed some installation issues because Windows users are not so familiar with having to compile code from source as memcache does not come with any installation software.

Follow the below steps to configure in XAMPP windows 10.

1) Enable the module Memcached.

It can be done by editing the php.ini file(As per my system setup location is E:\xampp\php\php.ini)

Serach for the text ‘;extension=php_memcache.dll’ andreplace it with ‘extension=php_memcache.dll’

If the text ‘;extension=php_memcache.dll’ is not available in php.ini file add the below content to it.


memcache.allow_failover = 1
memcache.chunk_size =8192
memcache.default_port = 11211

2) Download the necessary php_memecache.dll file.

You can download it form

Make sure that you are downloading the correct ‘php_memcache.dll’ file that align with the php version you are using.

Otherwise there us a chance to you might be getting the following error

PHP Warning: PHP Startup: Unable to load dynamic library ‘xampp\php\ext\php_memcache.dll’ – The specified module could not be found

3. Unzip the php_memcache.dll file and put it into your php ext folder. In my case its E:/xampp/php/ext/

4. Download memcached server for windows

You can download it from

5) Unzip and put the files in memcached folder into a desired directory (e.g. e:/memcached/)

8. Restart Xampp Apache

$memcache = new Memcache;
 $memcache->connect("localhost",11211); # You might need to set "localhost" to ""
 echo "Server's version: " . $memcache->getVersion() . "<br />\n";
 $tmp_object = new stdClass;
 $tmp_object->str_attr = "test";
