[xdebug]
xdebug.file_link_format="txmt://open?url=file://%f&line=%l"
xdebug.remote_enable=1
xdebug.remote_host=localhost
xdebug.remote_port=9000

$> php -m
You should see xdebug module in list.
$> sudo apachectl restart

phpinfo will output xdebug module.
After xdebug installed, then install PDT for eclipse, or download MacGDBp, php can debug using bleakpoint.
