I have Memcache installed and working for PHP apps run through Apache (v2.2) but when I try to run a .php file in the command-line i get this error:
Fatal error: Class 'Memcache' not found in /usr/local/Matters/app/matters-common/connection.php on line 94
Line 94 is:
$memcache = new Memcache;
Other info:
CentOS 5.2
PHP 5.2.5 (cli) (built: Feb 20 2008 21:13:12)
Zend Engine v2.2.0, Copyright (c) 1998-2007 Zend Technologies
Apache v2.2.8

Presumably you have separate php.ini files set up for apache and the command line (cli).
If so, you need to add the following to your cli php.ini file:
extension=memcache.so
On Ubuntu it's in /etc/php5/cli/php.ini
If it's working then memcache should appear in the list of modules if you run php -m on the command line.
Alternatively, you can create a file /etc/php5/cond.d/memcache.ini with the same contents.

It is possible that you have a separate php.ini file for CLI mode. This file might not include memcache extension.

I did have this kind of error and I also did php -i | grep memcache and it says memcache is enabled, but my solution that solved the problem was when I edited the php.ini, i simply modified the extension_dir="./" line to the full path of the extensions directory which now looked like this, extension_dir="/usr/local/lib" -- you need to check where the extension directory of the php reside and make sure memcache.so is there..
then i simply restarted httpd and alas the problem is gone.

For simplicity sake I used:
php -c /etc/php.ini ./cli-script.php

If you do not know which php.ini your command line is using, type php -i. You will get a long list of settings, where somewhere near the top of the list you will see which php.ini is being used:
Configuration File (php.ini) Path => /Applications/MAMP/bin/php/php5.3.6/conf
Loaded Configuration File => /Applications/MAMP/bin/php/php5.3.6/conf/php.ini
Scan this dir for additional .ini files => (none)
Additional .ini files parsed => (none)
