Thanks to nono303 on GitHub we can run this PHP extension and memcached on Windows! This is great for a dev environment to match a production unix server. I am using PHP 8.0 with this memcache extension on a Windows 10 box with a memcached server running on localhost and it is working great.
I can't post a link but the dll for this extension is at the repo: nono303/PHP-memcache-dll
And the actual memcached server for windows is at the repo: nono303/memcachedGOTCHA: Recently I was tasked with moving from PECL memcache to PECL memcached and ran into a major problem -- memcache and memcached serialize data differently, meaning that data written with one library can't necessarily be read with the other library.
For example, If you write an object or an array with memcache, it's interpreted as an integer by memcached. If you write it with memcached, it's interpreted as a string by memcache.
tl;dr - You can't safely switch between memcache and memcached without a either a cache flush or isolated cache environments.
<?php
$memcache = new Memcache;
$memcacheD = new Memcached;
$memcache->addServer($host);
$memcacheD->addServers($servers);
$checks = array(
123,
4542.32,
'a string',
true,
array(123, 'string'),
(object)array('key1' => 'value1'),
);
foreach ($checks as $i => $value) {
print "Checking WRITE with Memcache\n";
$key = 'cachetest' . $i;
$memcache->set($key, $value);
usleep(100);
$val = $memcache->get($key);
$valD = $memcacheD->get($key);
if ($val !== $valD) {
print "Not compatible!";
var_dump(compact('val', 'valD'));
}
print "Checking WRITE with MemcacheD\n";
$key = 'cachetest' . $i;
$memcacheD->set($key, $value);
usleep(100);
$val = $memcache->get($key);
$valD = $memcacheD->get($key);
if ($val !== $valD) {
print "Not compatible!";
var_dump(compact('val', 'valD'));
}
}Note that the Memcache 3.0.8 module DOES NOT WORK WITH PHP 7 (or higher)
There is an open bug about this - see https://bugs.php.net/bug.php?id=72887 and over 1 year old at time of writing - however, it appears that development of this module has been abandoned and the MemcacheD module is now the only way to access Memcache through PHP.
If you are writing a NEW tool, and you want to use Memcache, use the MemcacheD library. If you are trying to repair an old tool, you'll either have to stick with PHP 5.6, or, spend the time reworking your code to use MemcacheD.3.0.8 is not really compatible with PHP 7, but this fork seems to be working:
https://github.com/websupport-sk/pecl-memcache
For new projects, memcacheD sounds safer, but this fork might help to keep alive some legacy projects.
Debian package manager chose this version: https://github.com/websupport-sk/pecl-memcache/commit/4991c2fff22d00dc81014cc92d2da7077ef4bc86
