phpMyAdmin一直提示Warning.........mysqli_init()什么错误，且非常缓慢
不知道是不是配置的问题，我将mysql全部重装之后还是如此，用mysql的官方workbench没什么问题。
php中直接执行mysqli_init()也是报Property access is not allowed yet的错误。。。
------解决思路----------------------
不知楼主的问题现在是否解决。我最近几天也发现了这个问题，今天排查了一下，发现是之前安装的xdebug插件导致的，把php.ini中xdebug的配置项中的trace和profiler去掉之后，重启服务器就恢复正常了。
楼主可以参考下。
