Делюсь своим php.ini секцией [XDebug]…

[XDebug]
zend_extension = "C:\xampp\php\ext\php_xdebug.dll"
xdebug.profiler_enable = 1	
xdebug.profiler_output_dir = "C:\xampp\tmp"
xdebug.var_display_max_depth = -1 
xdebug.var_display_max_children = -1
xdebug.var_display_max_data = -1 
xdebug.remote_enable=1
xdebug.remote_handler="dbgp"
xdebug.remote_mode=req
xdebug.remote_port=9000
xdebug.remote_host=127.0.0.1
xdebug.remote_connect_back = 1
xdebug.idekey=netbeans-xdebug
xdebug.remote_autostart = "On"

Или проще

[XDebug]
zend_extension = "C:\xampp\php\ext\php_xdebug.dll"
xdebug.remote_enable = 1
xdebug.remote_handler = "dbgp"
xdebug.remote_host = "127.0.0.1"
