Using NetBeans to debug PHP?

UPDATE 1:

I have made a change in:

/etc/php5/apache2/conf.d/xdebug.ini

looks like this:

zend_extension=/usr/lib/php5/20090626+lfs/xdebug.so
xdebug.remote_enable=On
xdebug.remote_enable=1
xdebug.remote_host="localhost"
xdebug.remote_port=9000
xdebug.remote_handler="dbgp"

phpinfo looks like this:

I have checked netbeans tools > options > php settings and they are as they have been described in the first answer below. I then select an if statement, click ctrl+f8 an add a line break, and I am not sure what to do next, as most of the debug and run options in netbeans are disabled.

ORIGINAL QUESTION:

I have tried following many guides, but I can't seem to get php debugging in netbeans to work

I have installed lamp stack, netbeans, xdebug, netbeans php plugin, and added the following to /etc/php5/apache2/conf.d/xdebug.ini:

zend_extension=/usr/lib/php5/20090626+lfs/xdebug.so
xdebug.remote_enable=On
xdebug.remote_host="localhost"
xdebug.remote_port=9000
xdebug.remote_handler="dbgp"

If I then restart apache2 and load netbeans and open a php page and add a breakpoint, all the debug and run options are disabled in netbeans...

What am I doing wrong?

I am using ubuntu 10.04, and everything is installed via the standard ubuntu repositories.

Your xdebug settings seem fine, although you might need to add another line

xdebug.remote_enable=1

And you probably need to check/change a few settings in Netbeans. Go to Tools - Options - PHP - General and verify that the debugger port is set to 9000 (as is your xdebug port) and the session id is set to netbeans-xdebug

You can verify that xdebug is running when you go to a page that calls phpinfo() and check for xdebug in the output.
