When I upgraded my desktop to Ubuntu 10.04 (Lucid Lynx) I also upgraded my PHP version to 5.3. Apart from a few warnings with some deprecated functions (the main cuplrit being the ereg functions) all went well.

When using the Zend Tool command from the command line I started getting warnings about xdebug:

[email protected]: ~$ zf show version
PHP Warning:  Xdebug MUST be loaded as a Zend extension in Unknown on line 0
Zend Framework Version: 1.10.2

To fix this you need to change your extension loader in /etc/php5/cond.d/xdebug.ini to use zend_extension_ts:

extension=xdebug.so
;zend_extension=/usr/lib/php5/20090626+lfs/xdebug.so
zend_extension_ts=/usr/lib/php5/20090626+lfs/xdebug.so

xdebug.remote_enable=1
xdebug.remote_host=localhost
xdebug.remote_port=9000
xdebug.remote_handler=dbgp
