安装完成用admin账号登陆后，出现红色的框框显示这个：

网上查了一下，这是因为PHP 7.1.7类型强化，处理方法是找到Zabbix WEB目录下include/func.inc.php文件，修改它
sed -i '/$last = strtolower(substr($val, -1));/a$val = substr($val,0,-1);' func.inc.php
问题依然未能解决，后来查看了一下func.inc.php代码，跳转到报错的位置#410，通过网上的解决方法分析，应该是val这个变量类型问题，在403行后添加一行$val = substr($val,0,-1); 保存修改后的文件，重新访问zabbix web界面即可。
