您的php.ini配置文件引用了几个不存在的文件，例如/usr/lib/php/20131226/php_pdo_mysql.dll，您的php安装已损坏。重新安装PHP可能更容易，但如果您想手动修复它，请创建一个名为phpinfo.PHP的页面，并让它包含

<?php phpinfo(~0);

并在浏览器中打开它，您将获得php.ini的位置和解析的附加ini配置文件列表，一旦获得，扫描php.ini文件和所有附加配置文件，并删除所有引用到不存在的文件。例如在这个屏幕截图中：

在这里，您必须扫描文件/etc/php/7.0/fpm/php.ini和/etc/php/7.0/fpm/conf. d/10-mysqlnd.ini和/etc/php/7.0/fpm/conf. d/10-opcache.ini和/etc/php/7.0/fpm/conf. d/10-pdo.ini和/etc/php/7.0/fpm/conf. d/15-xml.ini和/etc/php/7.0/fpm/conf. d/20-calendar.ini和/etc/php/7.0/fpm/conf. d/20-ctype.ini和/etc/php/7.0/fpm/conf. d/20-curl.ini和/etc/php/7.0/fpm/conf. d/20-dom.ini和/etc/php/7.0/fpm/conf. d/20-exif.iniand/etc/php/7.0/fpm/conf. d/20-fileinfo.iniand/etc/php/7.0/fpm/conf. d/20-ftp.iniand/etc/php/7.0/fpm/conf. d/20-gd.ini和/etc/php/7.0/fpm/conf. d/20-gettext.ini和/etc/php/7.0/fpm/conf. d/20-iconv.ini和/etc/php/7.0/fpm/conf. d/20-json.ini和/etc/php/7.0/fpm/conf. d/20-mbstring.ini和/etc/php/7.0/fpm/conf. d/20-mysqli.ini和/etc/php/7.0/fpm/conf. d/20-pdo_mysql.ini和/etc/php/7.0/fpm/conf. d/20-pdo_sqlite.iniand/etc/php/7.0/fpm/conf. d/20-phar. iniand/etc/php/7.0/fpm/conf. d/20-posx. iniand/etc/php/7.0/fpm/conf. d/20-readline. iniand/etc/php/7.0/fpm/conf. d/20-shmop. iniand/etc/php/7.0/fpm/conf. d/20-简单化exml. iniand/etc/php/7.0/fpm/conf. d/20-插座. iniand/etc/php/7.0/fpm/conf. d/20-sqlite3. iniand/etc/php/7.0/fpm/conf. d/20-ssh2.iniand/etc/php/7.0/fpm/conf. d/20-sysvmsg. iniand/etc/php/7.0/fpm/conf. d/20-sysvsem. iniand/etc/php/7.0/fpm/conf. d/20-sysvshm. iniand/etc/php/7.0/fpm/conf. d/20-Tokenizer. ini>和/etc/php/7.0/fpm/conf. d/20-wddx. ini和/etc/php/7.0/fpm/conf. d/20-xdebug. ini和/etc/php/7.0/fpm/conf. d/20-xmlreader. ini和/etc/php/7.0/fpm/conf. d/20-xmlWriter. ini和/etc/php/7.0/fpm/conf. d/20-xsl. ini对不存在的文件的引用，并删除这些引用

（但说真的，您最好重新安装所需的PHP版本。根据您的评论，我看到您已经安装了多个PHP版本。）
