If you have error with libtool version after make - way to install:
phpize --clean && phpize
rm aclocal.m4
aclocal
autoconf
./configure
make
make install
[memcache-2.2.6, gentoo.x86-64]

On Slackware, after copilling it, you should copy the file /module/memcache.so to /usr/lib/httpd/modules. Then, the instruction extension=memcache.so must be added into the file /etc/httpd/php.ini
Restart the httpd and it should work!

It is very important to note when reading the information supplied by others on this page that there are two *distinct* memcache PHP implementations for the service "memcached".
1) pecl-memcache
2) pecl-memcached
This page is for the first, pecl-memcache.
If you are looking for pecl-memcached information, visit here:

wget http://danga.com/memcached/dist/memcached-1.2.6.tar.gz
tar xfz memcached-1.2.6.tar.gz
cd memcached-1.2.6
./configure && make && sudo make install

# Run memcached as a daemon (d = daemon, m = memory, u = user, l = IP to listen to, p = port)
memcached -d -m 1024 -u root -l 127.0.0.1 -p 11211

<?php
$memcache = new Memcache;
$memcache->connect('localhost', 11211) or die ("Could not connect");

$version = $memcache->getVersion();
echo "Server's version: ".$version."<br/>\n";

$tmp_object = new stdClass;
$tmp_object->str_attr = 'test';
$tmp_object->int_attr = 123;

$memcache->set('key', $tmp_object, false, 10) or die ("Failed to save data at the server");
echo "Store data in the cache (data will expire in 10 seconds)<br/>\n";

$get_result = $memcache->get('key');
echo "Data from the cache:<br/>\n";

var_dump($get_result);
?>

# Test to see if the file renders in your browser

Cheers!

on Fedora, apparently
yum install php-pecl-memcache

Newer PHP versions don't have a --enable-memcache options; simply installing the PECL package will be enough... so to be absolutely clear, you WON'T have to recompile PHP to use memcache. That paragraph above seems like a bad case of earlier version documentation editing.
