owncloud安装出现：PHP is apparently set up to strip inline doc blocks. This will make several

先查看phpinfo，找到opcache的配置文件。我的是独立出来的放在：/usr/local/php/etc/php.d/opcache.ini。

opcache.enable_cli=0
opcache.enable=0 

/bin/systemctl restart  php-fpm.service
访问后再修改为1像上面这样restart一下即可。
打开页面看到如下错误：“PHP is apparently set up to strip inline doc blocks. This will make several core apps inaccessible.”这可能是由缓存/加速器造成的，例如 Zend OPcache 或 eAccelerator。打开你的打开php.ini文件，找到：[opcache]，设置为：opcache.enable=0 和 opcache.enable_cli=0。

[opcache]
opcache.enable=0 
opcache.enable_cli=0
