xdebug does not activate the breakpoint

问题

I am using Netbeans to do my project(codeigniter) and my xdebug is configured in php ini. The following are the setting:

zend_extension = "C:\xampp\php\ext\php_xdebug.dll"
;xdebug.profiler_append = 0
;xdebug.profiler_enable = 1
;xdebug.profiler_enable_trigger = 0
;xdebug.profiler_output_dir = "C:\xampp\tmp"
;xdebug.profiler_output_name = "cachegrind.out.%t-%s"
xdebug.remote_enable = 1
xdebug.remote_handler = "dbgp"
xdebug.remote_host = "127.0.0.1"
xdebug.remote_autostart = 1
xdebug.idekey = "netbeans-xdebug"
xdebug.remote_log="C:\xampp\tmp\xdebug.log"
xdebug.remote_port=9001

Php info shows that xdebug is activated. I set the breakpoint at on of the variable in the login method and started to debug. The link at the login page appears:

localhost/goldilock/index.php?XDEBUG_SESSION_START=netbeans-xdebug

After login in, the breakpoint is not activated and I can't debug and the XDEBUG_SESSION_START=netbeans-xdebug part of the link disappears.

Is there any way the debugging can be activated. I can't find any solution to activate the debugger to the breakpoint.

The xdebug.log says the following:

First of all, you do need to turn on xdebug.remote_enable=1 — without that, debugging is not activated and it will not work.

For requests after the first "login", xdebug.remote_autostart should deal with that, but it is possible that Netbeans doesn't accept the new incoming debugging connection. To find out what Xdebug is trying to do, add the setting xdebug.remote_log=c:\temp\xdebug.log and investigate what's in the log. (You might have to change the path).
