xdebug.remote_host = 192.168.59.104//Note here is that the client's ip< is the IP of the IDE's machine, not your web server>
Xdebug.remote_port = 9900//Note here is the port of the client < The IP of the IDE's machine, not your web server>
xdebug.remote_enable = on
Xdebug.remote_handler = DBGP
Xdebug.remote_log = "/var/www/xdebug/xdebug.log"
xdebug.remote_req = req
xdebug.auto_trace = Off
Xdebug.remote_autostart = on
xdebug.show_exception_trace = 0
xdebug.collect_vars = on
Xdebug.collect_return = on
xdebug.collect_params = on
xdebug.var_display_max_depth =
xdebug.show_local_vars = 1
xdebug.dump_undefined = 1
xdebug.profiler_enable = 1

Phpstorm configuration:
1.file->setings->php| Debug to the right. That piece of xdebug. Set the Debug port:9900 (set here is, Xdebug spits out the debug information, through what port of this machine transmits. ）

2.file->setings->php|  Servers to the right.   Host: Your Web server's domain name or IP, port, the following use path mapping means, the directory of your project, the corresponding server, what directory? It must be set here! Otherwise, a file cannot be found and an error occurs, which leads to the debug termination.

3.run->edit Configurations-> Adds a PHP WEB application to the tuning pilot.  Right: Server selects the server you created above. StartURL Set your portal file.

At this point, the configuration is complete!

Such a request, you can register a debugging client Oh!
