Windows cmd.exe未显示实际的php版本

Recently i have installed xampp update version which have php 5.6 version. In my c drive i have older version of xampp, i renamed it by xampp_old. My new xampp installation files in C:\xampp. When i try to get php version by my cmd.exe by php -v command it show older php version (php 5.4.24).I have checked my cmd uses the C:\Program Files\iis express\PHP\v5.4\php.ini file. How can i set the new php.ini file for my cmd.exe from the c:\xampp\php

Run the php command in the c:\xampp folder. If it's still showing the old version, replace the path in your System Environment Variables.

1. Start -> type: Edit the system environment variables
2. Click Environment variables (lower right corner)
3. Under system variables -> Select and edit PATH
4. Replace the old folder or add c:\xampp\php; in the Variable value field
