问题
I am on windows 7, 64bit, with xampp 3.2.1 installed . I got my xdebug dll file through the xdebug.org wizard, and put it where the wizard told me to, C:\xampp\php\etc. Then I made sure to modify the correct (and as far as I'm aware only) php.ini file at C:\xampp\php\php.ini. This is the same ini that phpinfo() reports.
When I run php -m , I can see the xDebug extension listed twice, just as it should be. But going back to a phpinfo() output, the extension is not listed.
I've tried restarting my computer, apache. If I try to run this script to test if xdebug is working, it gives me a error
socket_bind(): unable to bind address [10048]:Only one usage of each socket address (protocol/network address/port) is normally permitted

After hours of hair pulling... and a nap, I came across this config code and it somehow worked. Now that the extension is on firm ground, I can start carefully adding or removing features one at a time.
zend_extension = "C:\xampp\php\ext\php_xdebug-2.2.5-5.5-vc11.dll" // whatever your file name is
xdebug.remote_autostart=on
xdebug.remote_enable=on
xdebug.remote_enable=1
xdebug.remote_handler="dbgp"
xdebug.remote_host= "localhost"
xdebug.remote_port=9000
xdebug.remote_mode=req
xdebug.idekey="netbeans-xdebug"
The root problem was a messed up php.ini file. The problem is that xampp's php.ini has some defaults listed there that we are told to uncomment by xdebug,netbeans, other online guides. Unfortunately, given the certain combinations of values, that just didn't work. This list of parameters definitely worked for me though.
