php程序总是提示验证码输入有误解决方案，php验证码
今天在将一套程序放到其他服务器上执行的时候，发现后台的登录验证码不管输入正确与否，总是显示：
验证码输入有误
接着就开始debug了。
因为正确的验证码结果已经经过加密之后保存在了session中，所有用于输入的验证码会跟session中的进行比对，从而判断验证码是否输入有误!
既然老是显示："验证码输入有误"
说明session中保存到结果可能有问题。然后，dump下session，发现结果为null......
解决办法：使用phpinfo查看session信息，找出session的保存路径，然后给其设置写入的权限即可
注：记得重启apache或iis
