Figuring out memcache for mamp/php

install.txt

@see http://www.re-cycledair.com/installing-memcache-on-mamp

Step 1: Install XCode

Step 2: Make the MAMP PHP binary files executable
sudo chmod +xrw /Applications/MAMP/bin/php5.3/bin/p*

Step 3: Get the Memcache extension source
cd ~
wget http://pecl.php.net/get/memcache-2.2.5.tgz
tar -zxvf memcache-2.2.5.tgz
cd memcache-2.2.5

Step 4: PHPize the Memcache extension files
/Applications/MAMP/bin/php5.3/bin/phpize

Step 5: Compile the Memcache extension
./configure
make

*If this configure doesnt work, and you're on a snow leopard arch, try this -
CFLAGS=-m32 CPPFLAGS=-m32 CCASFLAGS=-m32 ./configure
make
sudo make install

Step 6: Add the extension to the PHP.ini file
Add the following to the end of your PHP 5.3 ini file via the MAMP file menu.
extension=memcache.so

Step 7: Copy the memcache extension to the PHP extension folder
cp modules/memcache.so /Applications/MAMP/bin/php5.3/lib/php/extensions/no-debug-non-zts-[yourtimestamp]/

memtest.php

<?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);

?>

Mamp is not reflecting memcache enabled in phpinfo. APC, Xcache display, however.

Potential command to run-

Got memcache to work via this links help - http://bit.ly/wgVm4m

phpize
CFLAGS=-m32 CPPFLAGS=-m32 CCASFLAGS=-m32 ./configure
make
sudo make install

It was important not to ./configure with-php-config="/Applications/MAMP/..." that last parameter, killed it. This was for a 10.6.8 quad xeon processor arch - macosx snow leopard.

This is a great tutorial on using memcache - http://www.search-this.com/2007/07/24/an-introduction-to-memcached/

Got the php.net example to work by following this tutorial -

"One thing I experienced, re: start/stopping with MAMP. I found I was getting Connection Refused (61) errors in PHP, which were due to the memcached process not running at all.

I needed to make the following modifications to the startMemcached.sh script:
/usr/local/bin/memcached -m 24 -p 11211 -u user -d

1. The full path needed to be added (alternately probably could do this with $PATH)
2. Since MAMP was starting/stopping things as root, the -u user had to be added to tell it what user to impersonate (memcached won't run as root). Obviously "user" should be replaced with an actual user name..."
