我使用的xamp 搭建的的php集成环境。
默认情况下，xamp没有开启xdebug功能，但是x-debug dll及配置文件均已写入php.ini 中了。
1. 启用x-debug：
php.ini 去掉1008行注释：
zend_extension = "D:/Program Files/XAMPP/xampp/php/ext/php_xdebug.dll"
参考http://netbeans.org/kb/docs/php/debugging_zh_CN.html
2. 开启php.ini 中的调试功能
; xdebug.auto_trace ; Type: boolean, Default value: 0 ; When this setting is set to on, the tracing of function calls will be enabled just before the ; script is run. This makes it possible to trace code in the auto_prepend_file. xdebug.auto_trace = 0 ; xdebug.collect_includes ; Type: boolean, Default value: 1 ; This setting, defaulting to On, controls whether Xdebug should write the filename used in include ; (), include_once(), require() or require_once() to the trace files. xdebug.collect_includes = 1 ; xdebug.collect_params ; Type: integer, Default value: 0 ; ; This setting, defaulting to 0, controls whether Xdebug should collect the parameters passed to ; functions when a function call is recorded in either the function trace or the stack trace. xdebug.collect_params = 0 ; xdebug.collect_return ; Type: boolean, Default value: 0 ; This setting, defaulting to Off, controls whether Xdebug should write the return value of function ; calls to the trace files. xdebug.collect_return = 0 ; xdebug.collect_vars ; Type: boolean, Default value: Off ; This setting tells Xdebug to gather information about which variables are used in a certain scope. ; This analysis can be quite slow as Xdebug has to reverse engineer PHP's opcode arrays. This setting ; will not record which values the different variables have, for that use xdebug.collect_params. This ; setting needs to be enabled only if you wish to use xdebug_get_declared_vars(). xdebug.collect_vars = "Off" ; xdebug.default_enable ; Type: boolean, Default value: On ; If this setting is On then stacktraces will be shown by default on an error event. You can disable ; showing stacktraces from your code with xdebug_disable(). As this is one of the basic functions of ; Xdebug, it is advisable to leave this setting set to 'On'. xdebug.default_enable = "On" ; xdebug.dump.* ; Type: string, Default value: Empty ; * = COOKIE, FILES, GET, POST, REQUEST, SERVER, SESSION. These seven settings control which data ; from the superglobals is shown when an error situation occurs. Each php.ini setting can consist of ; a comma seperated list of variables from this superglobal to dump, but make sure you do not add ; spaces in this setting. In order to dump the REMOTE_ADDR and the REQUEST_METHOD when an error ; occurs, add this setting: ; ; xdebug.dump.SERVER = REMOTE_ADDR,REQUEST_METHOD ; xdebug.dump.SERVER = REMOTE_ADDR,REQUEST_METHOD ;xdebug.dump.COOKIE = "" ;xdebug.dump.FILES = "" ;xdebug.dump.GET = "" ;xdebug.dump.POST = "" ;xdebug.dump.REQUEST = "" ;xdebug.dump.SERVER = "" ;xdebug.dump.SESSION = "" ; xdebug.dump_globals ; Type: boolean, Default value: 1 ; Controls whether the values of the superglobals as defined by the xdebug.dump.* settings whould be ; shown or not. xdebug.dump_globals = 1 ; xdebug.dump_once ; Type: boolean, Default value: 1 ; Controls whether the values of the superglobals should be dumped on all error situations (set to ; Off) or only on the first (set to On). xdebug.dump_once = 1 ; xdebug.dump_undefined ; Type: boolean, Default value: 0 ; If you want to dump undefined values from the superglobals you should set this setting to On, ; otherwise leave it set to Off. xdebug.dump_undefined = 0 ; xdebug.extended_info ; Type: integer, Default value: 1 ; Controls whether Xdebug should enforce 'extended_info' mode for the PHP parser; this allows Xdebug ; to do file/line breakpoints with the remote debugger. When tracing or profiling scripts you ; generally want to turn off this option as PHP's generated oparrays will increase with about a third ; of the size slowing down your scripts. This setting can not be set in your scripts with ini_set(), ; but only in php.ini. xdebug.extended_info = 1 ; xdebug.file_link_format ; Type: string, Default value: *empty string* , Introduced in Xdebug 2.1 ; ; This setting determines the format of the links that are made in the display of stack traces where ; file names are used. This allows IDEs to set up a link-protocol that makes it possible to go ; directly to a line and file by clicking on the filenames that Xdebug shows in stack traces. ;xdebug.file_link_format = "" ; xdebug.idekey ; Type: string, Default value: *complex* ; Controls which IDE Key Xdebug should pass on to the DBGp debugger handler. The default is based on ; environment settings. First the environment setting DBGP_IDEKEY is consulted, then USER and as last ; USERNAME. The default is set to the first environment variable that is found. If none could be ; found the setting has as default ''. ;xdebug.idekey = "" ; xdebug.manual_url ; Type: string, Default value: http://www.php.net ; This is the base url for the links from the function traces and error message to the manual pages ; of the function from the message. It is advisable to set this setting to use the closest mirror. ;xdebug.manual_url = "http://www.php.net" ; xdebug.max_nesting_level ; Type: integer, Default value: 100 ; Controls the protection mechanism for infinite recursion protection. The value of this setting is ; the maximum level of nested functions that are allowed before the script will be aborted. ;xdebug.max_nesting_level = 100 ; xdebug.overload_var_dump ; Type: boolean, Default value: 1 , Introduced in Xdebug 2.1 ; By default Xdebug overloads var_dump() with its own improved version for displaying variables when ; the html_errors php.ini setting is set to 1. In case you do not want that, you can set this setting ; to 0, but check first if it's not smarter to turn off html_errors. ;xdebug.overload_var_dump = 1 ; xdebug.profiler_append ; Type: integer, Default value: 0 ; When this setting is set to 1, profiler files will not be overwritten when a new request would map ; to the same file (depnding on the xdebug.profiler_output_name setting. Instead the file will be ; appended to with the new profile. xdebug.profiler_append = 0 ; xdebug.profiler_enable ; Type: integer, Default value: 0 ; Enables Xdebug's profiler which creates files in the profile output directory. Those files can be ; read by KCacheGrind to visualize your data. This setting can not be set in your script with ini_set ; (). xdebug.profiler_enable = 0 ; xdebug.profiler_enable_trigger ; Type: integer, Default value: 0 ; When this setting is set to 1, you can trigger the generation of profiler files by using the ; XDEBUG_PROFILE GET/POST parameter. This will then write the profiler data to defined directory. xdebug.profiler_enable_trigger = 0 ; xdebug.profiler_output_dir ; Type: string, Default value: /tmp ; The directory where the profiler output will be written to, make sure that the user who the PHP ; will be running as has write permissions to that directory. This setting can not be set in your ; script with ini_set(). xdebug.profiler_output_dir = "D:/Program Files/XAMPP/xampp/tmp" ; xdebug.profiler_output_name ; Type: string, Default value: cachegrind.out.%p ; ; This setting determines the name of the file that is used to dump traces into. The setting ; specifies the format with format specifiers, very similar to sprintf() and strftime(). There are ; several format specifiers that can be used to format the file name. ; ; See the xdebug.trace_output_name documentation for the supported specifiers. xdebug.profiler_output_name = "xdebug_profile.%p" ; xdebug.remote_autostart ; Type: boolean, Default value: 0 ; Normally you need to use a specific HTTP GET/POST variable to start remote debugging (see Remote ; Debugging). When this setting is set to 'On' Xdebug will always attempt to start a remote debugging ; session and try to connect to a client, even if the GET/POST/COOKIE variable was not present. xdebug.remote_autostart = 0 ; xdebug.remote_enable ; Type: boolean, Default value: 0 ; This switch controls whether Xdebug should try to contact a debug client which is listening on the ; host and port as set with the settings xdebug.remote_host and xdebug.remote_port. If a connection ; can not be established the script will just continue as if this setting was Off. xdebug.remote_enable = 1 ; xdebug.remote_handler ; Type: string, Default value: dbgp ; Can be either 'php3' which selects the old PHP 3 style debugger output, 'gdb' which enables the GDB ; like debugger interface or 'dbgp' - the brand new debugger protocol. The DBGp protocol is more ; widely supported by clients. See more information in the introduction for Remote Debugging. xdebug.remote_handler = "dbgp" ; xdebug.remote_host ; Type: string, Default value: localhost ; Selects the host where the debug client is running, you can either use a host name or an IP ; address. xdebug.remote_host = "localhost" ; xdebug.remote_log ; Type: string, Default value: none ; If set to a value, it is used as filename to a file to which all remote debugger communications are ; logged. The file is always opened in append-mode, and will therefore not be overwritten by default. ; There is no concurrency protection available. ;xdebug.remote_log = "none" ; xdebug.remote_mode ; Type: string, Default value: req ; ; Selects when a debug connection is initiated. This setting can have two different values: ; ; req ; Xdebug will try to connect to the debug client as soon as the script starts. ; jit ; Xdebug will only try to connect to the debug client as soon as an error condition occurs. ;xdebug.remote_mode = "req" ; xdebug.remote_port ; Type: integer, Default value: 9000 ; The port to which Xdebug tries to connect on the remote host. Port 9000 is the default for both the ; client and the bundled debugclient. As many clients use this port number, it is best to leave this ; setting unchanged. xdebug.remote_port = 9000 ; xdebug.show_exception_trace ; Type: integer, Default value: 0 ; When this setting is set to 1, Xdebug will show a stack trace whenever an exception is raised - ; even if this exception is actually caught. ;xdebug.show_exception_trace = 0 ; xdebug.show_local_vars ; Type: integer, Default value: 0 ; When this setting is set to something != 0 Xdebug's generated stack dumps in error situations will ; also show all variables in the top-most scope. Beware that this might generate a lot of ; information, and is therefore turned off by default. ;xdebug.show_local_vars = 0 ; xdebug.show_mem_delta ; Type: integer, Default value: 0 ; When this setting is set to something != 0 Xdebug's human-readable generated trace files will show ; the difference in memory usage between function calls.

The setting ; specifies the format with format specifiers, very similar to sprintf() and strftime(). There are ; several format specifiers that can be used to format the file name. The '.xt' extension is always ; added automatically. ;xdebug.trace_output_name = "trace.%c" ; xdebug.var_display_max_children ; Type: integer, Default value: 128 ; Controls the amount of array children and object's properties are shown when variables are ; displayed with either xdebug_var_dump(), xdebug.show_local_vars or through Function Traces.

需要注意的是：要将
xdebug.remote_enable = 1
值设置为1，否则无法进行断点调试。
相关php断点调试，可参考NetBeans 官方教程：
http://netbeans.org/kb/docs/php/debugging_zh_CN.html
虽然不如VS那么强大，但是基本功能都还是有的。
