| INSTALLATION INSTRUCTIONS |
| ========================= |
| |
| See http://xdebug.org/install.php#configure-php for instructions |
| on how to enable Xdebug for PHP. |
| |
| Documentation is available online as well: |
| - A list of all settings: http://xdebug.org/docs-settings.php |
| - A list of all functions: http://xdebug.org/docs-functions.php |
| - Profiling instructions: http://xdebug.org/docs-profiling2.php |
| - Remote debugging: http://xdebug.org/docs-debugger.php |
| |
| |
| NOTE: Please disregard the message |
| You should add "extension=xdebug.so" to php.ini |
| that is emitted by the PECL installer. This does not work for |
| Xdebug. |

PHPSTORM 配置：
1.file->setings->php|Debug右侧。xdebug的那一块。
设置Debug port:9900（这里设置 的是，xdebug 吐出的debug信息，通过本机的什么端口传输。）
DBGp IdeKey phpstorm_data_well_tmp_php
2.file->setings->php|Servers 右侧。
host: 你的web服务器的域名或ip ,端口， 下面的 use path mapping 意的是，你的项目的目录，对应服务器上的，什么目录？
这里一定要设置哦！ 不然，会发生找不到文件而出错，导至调试终止。
3.Run->Edit Configurations-> 增加一个 PHP WEB APPlication 的调试点。
右侧： server 选择你上面建立的server. starturl 设置你的入口文件。
至此，配置完毕！
