php版本升级切换

1.下载对应不带 nts 的php版本（http://windows.php.net/download/），然后解压放到\laragon\bin\php目录下

2.记得改环境变量下php的path配置

3.laragon操作：菜单->PHP->版本->选择对应的php版本

4.需要重新配置下xdebug

 php.ini最后加

[xdebug]zend_extension="D:\laragon\bin\php\php-7.1.14-Win32-VC14-x64\ext\php_xdebug.dll"xdebug.remote_enable=true    xdebug.remote_host=127.0.0.1 xdebug.remote_port=9000      xdebug.remote_handler=dbgpxdebug.idekey="PHPSTORM"

下载安装对应版本xdebug：php_xdebug.dll

放到对应php的ext文件夹下即可
