How to install memcache in MAMP

Question

I'm trying to install memcache in my MAMP installation, using various ressources on the web.

I'm on Mac OS 10.10.3
MAMP 3.4
PHP 5.6.10
xCode installed

• I installed memcache.so following https://github.com/majksner/php-memcached-mamp
• I installed homebrew to install autoconf
• Following https://stackoverflow.com/a/24392609/486529 :
  • I downloaded the PHP source on http://php.net/releases/
  • I created the folder /Applications/MAMP/bin/php/php5.X.X/include, and putted the downloaded folder in it.
  • I ran ./configure in /Applications/MAMP/bin/php/php5.X.X/include/php/
• I ran ./pecl install memcache in /Applications/MAMP/bin/php/php5.X.X/bin/
• I answered "no" to the question about session handler (I tryed yes, but something is missing, and not sure I need it)

• When I restard MAMP, I get the following error :

  [28-Aug-2015 10:53:55 Europe/Berlin] PHP Warning: PHP Startup: Unable to load dynamic library '/Applications/MAMP/bin/php/php5.6.10/lib/php/extensions/no-debug-non-zts-20131226/memcached.so' - dlopen(/Applications/MAMP/bin/php/php5.6.10/lib/php/extensions/no-debug-non-zts-20131226/memcached.so, 9): Library not loaded: /usr/local/lib/libmemcached.11.dylib

  Referenced from: /Applications/MAMP/bin/php/php5.6.10/lib/php/extensions/no-debug-non-zts-20131226/memcached.so

  Reason: image not found in Unknown on line 0

What did I missed ? Is it necessary to change the PHP path ? (by now, which php returns /usr/bin/php and not the MAMP one)

Edit : I noticed I forgotted to install dependencies (following https://github.com/majksner/php-memcached-mamp) :

$ brew install memcached
$ brew install libmemcached

So now, the error on MAMP startup is gone, but when I try to use Memcache on a php script, I get the following error :

PHP Fatal error: Class 'Memcache' not found in /Applications/MAMP/htdocs/crm/application/core/MY_Controller.php on line 9

Edit 2 :

I'm stupid : I mixed memcache and memcached ! there are not the same !

So I just have to add extension=memcache.so in my php.ini to make it work !

Edit 3 : Don't forget to launch memcached server :

/usr/local/bin/memcached -d -m 512 -l 127.0.0.1 -p 11211

(I suppose I'll to do that at every restart, or put it somewhere for autostart)

Thanks a lot.
