希望有人能帮助我。所以我想安装需要禁用 magicquotes 的 MediaWiki，所以我做了以下操作：
463 apt-add-repository ppa:ondrej/php5-oldstable
464 sudo apt-add-repository ppa:ondrej/php5
465 sudo apt-add-repository ppa:ondrej/php5-5.6
466 apt-add-repository ppa:ondrej/php5-oldstable
467 apt-get update
468 apt-get install php5
484 nano /etc/php5/apache2/php.ini // went to turn off magicquotes. Didn't work.
485 apt-get purge libapache2-mod-php5 php5 && apt-get install libapache2- mod-php5 php5
488 service apache2 restart
489 service apache2 stop
490 pidof apache2
491 skill -9 pid
492 service apache2 start
.............我破坏了 Apache。网站现在无法工作，我陷入困境。
以下是我目前所做的：
sudo add-apt-repository --remove ppa:ondrej/php5-oldstable
sudo add-apt-repository --remove ppa:ondrej/php5
sudo add-apt-repository --remove ppa:ondrej/php5-5.6
apt-get update
apt-get upgrade
apt-get purge libapache2-mod-php5 php5 && apt-get install libapache2-mod-php5 php5
