给新装的虚拟机安装lamp环境，安装到xdebug的时候突然怎么也断不下来，怎么回事？？？原来是xdebug新版本的配置文件写法有了变化：

版本为2.xx的xdebug：

zend_extension=xdebug.so 
xdebug.remote_enable=1
xdebug.remote_autostart=1
xdebug.remote_host=127.0.0.1
xdebug.remote_port=9000
xdebug.remote_handler=dbgp
xdebug.idekey=PHPSTORM

PHP Debug Adapter for Visual Studio Code 一文中对3.xx版本的xdebug配置变化进行了说明：

Enable remote debugging in your php.ini:

For XDebug v3.x.x:

xdebug.mode = debug
xdebug.start_with_request = yes
xdebug.client_port = 9000

For XDebug v2.x.x:

xdebug.remote_enable = 1
xdebug.remote_autostart = 1

所以新版配置如下：

zend_extension=xdebug.so 
xdebug.mode = debug 
xdebug.start_with_request = yes 
xdebug.client_port = 9000 
xdebug.remote_host=127.0.0.1 
xdebug.remote_handler=dbgp 
xdebug.idekey=PHPSTORM
