For : "memcache" can mean two things — the memcached caching server, or a PHP client extension named memcache/memcached. Most installations need the memcached server; on Windows the best, least brittle options today are Docker, WSL2 (Linux inside Windows), or a community Windows package. Official memcached info is at memcached.org.

Recommended quick methods:

  • Docker (recommended for modern Windows)

    docker run --name memcached -p 127.0.0.1:11211:11211 -d memcached

    This runs the official Linux memcached container and binds the port only to localhost. See the official image on Docker Hub: memcached.

  • WSL2 (run the Linux package inside Ubuntu/WSL)

    sudo apt update
sudo apt install memcached libmemcached-tools
sudo service memcached start   # or sudo systemctl start memcached

    This uses the native Linux package and tools; Windows apps can talk to memcached via 127.0.0.1.

  • Native Windows package (if you need a native exe)

    choco install memcached

    Chocolatey hosts community builds: . Follow the package notes to register as a Windows service if needed.

Keep security and testing in mind: memcached listens on TCP/UDP 11211 and has no built-in auth. Do not expose it to the public Internet; bind to localhost or use firewall rules. Quick checks:

telnet 127.0.0.1 11211
# or in PowerShell:
Test-NetConnection -ComputerName 127.0.0.1 -Port 11211

If the goal is a PHP app, choose the correct client extension (memcache vs memcached) for your PHP version; see the PHP manual for details: memcached extension.
