There are two extensions for memcached in PHP, "<a href="http://pecl.php.net/package/memcache" rel="noreferrer">memcache</a>" and "<a href="http://pecl.php.net/package/memcached" rel="noreferrer">memcached</a>". 

It looks like you're trying to use one ("memcache"), but the other is installed ("memcached").

blocks|key|3049357|text|右边是php_memcache.dll.在我的例子中，我使用的是用vc9编译的lib，而不是vc6编译器。在apatche错误日志中，我得到了如下内容：|type|unstyled|depth|inlineStyleRanges|offset|length|style|BOLD|entityRanges|data|3049358|3049359|+PHP启动:+sqlanywhere:无法初始化使用build+ID=API20090626编译的模块模块，TS，VC9+PHP使用build+ID=API20090626，TS，VC6编译的PHP这些选项需要匹配|blockquote|3049360|3049361|3049362|检查是否有相同的日志，并尝试下载使用不同编译器编译的不同dll。|3049363|entityMap^0|3|G|0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|P|8|@$9|Q|A|R|B|C]]|D|@]|E|$]]|$1|F|3|-4|5|6|7|S|8|@]|D|@]|E|$]]|$1|G|3|H|5|I|7|T|8|@]|D|@]|E|$]]|$1|J|3|-4|5|6|7|U|8|@]|D|@]|E|$]]|$1|K|3|-4|5|6|7|V|8|@]|D|@]|E|$]]|$1|L|3|M|5|6|7|W|8|@]|D|@]|E|$]]|$1|N|3|-4|5|6|7|X|8|@]|D|@]|E|$]]]|O|$]]

The right is php_memcache.dll. In my case i was using lib compiled with vc9 instead of vc6 compiler. In apatche error logs i got something like:

<blockquote>
 PHP Startup: sqlanywhere: Unable to
 initialize module Module compiled with
 build ID=API20090626, TS,VC9 PHP

</blockquote>

Check if you have same log and try downloading different dll that are compiled with different compiler.

I found the working dll files for PHP 5.4.4

I don't knowhow stable they are but they work for sure. Credits goes to this link.

It is the 2.2.5.0 version, I noticed after compiling it (for PHP 5.4.4).

Please note that it is not 2.2.6 but works. I also mirrored them in my own FTP. Mirror links:

Dispite what the accepted answer says in the comments, the correct way to install 'Memcache' is:

<pre><code>sudo apt-get install php5-memcache
</code></pre>

NOTE Memcache &amp; Memcached are two distinct although related pieces of software, that are often confused.

EDIT
As this is now an old post I thought it worth mentioning that you should replace php5 with your php version number.

For OSX users:

Run the following command to install Memcached:

<pre><code>brew install memcached

I've pasted the example from <a href="http://www.php.net/manual/en/memcache.examples-overview.php" rel="noreferrer">php.net</a> for using memcached in php and I'm getting:
<pre><code>Fatal error: Class 'Memcache' not found
</code></pre>
I have this in my php.ini:
<blockquote>
[memcache] 
memcache.hash_strategy = &quot;consistent&quot; 
memcache.max_failover_attemps = 100 
memcache.allow_failover = 1
</blockquote>
Here's info from php -i and php -m respectively:
<blockquote>
php -i | grep -i memcache 
memcached 
memcached support =&gt; enabled 
libmemcached version =&gt; 0.37 
Registered save handlers =&gt; files user sqlite memcached
php -m | grep -i memcache 
memcached
</blockquote>
So php seems to have loaded memcached as a module, and php info says that it is loaded and is using v .37. I have not tried yet via apache, I've only been using this through cli right now. Any thoughts?
