如何在Debian GNU / Linux 7上将PHP 5.4升级到PHP 5.6（简述）

我已经将这些行添加到 /etc/apt/sources.list

deb http://packages.dotdeb.org wheezy-php56 all
deb-src http://packages.dotdeb.org wheezy-php56 all

但是还是sudo apt-get update还是sudo apt-get upgrade不要碰PHP。

php --version 还是

PHP 5.4.39-0+deb7u2 (cli) (built: Mar 25 2015 08:33:29) 

（更新）试试这个（Ubuntu）：

sudo add-apt-repository ppa:ondrej/php -y
sudo apt-get update
sudo apt-get install php5.6-fpm -y

（更新） 对于Debian Wheezy（带有sudo）

echo "deb http://packages.dotdeb.org wheezy-php56 all" >> /etc/apt/sources.list.d/dotdeb.list
echo "deb-src http://packages.dotdeb.org wheezy-php56 all" >> /etc/apt/sources.list.d/dotdeb.list
wget http://www.dotdeb.org/dotdeb.gpg -O- | apt-key add - 
apt-get update
apt-get install php5-cli php5-fpm ….. (or whatever package you might need)

（更新21/06/2017） 对于Debian 8（jessie）

sudo nano /etc/apt/sources.list

添加以下存储库：

...
deb http://mirrors.digitalocean.com/debian jessie main contrib non-free
deb-src http://mirrors.digitalocean.com/debian jessie main contrib non-free

deb http://security.debian.org/ jessie/updates main contrib non-free
deb-src http://security.debian.org/ jessie/updates main contrib non-free

# jessie-updates, previously known as 'volatile'
deb http://mirrors.digitalocean.com/debian jessie-updates main contrib non-free
deb-src http://mirrors.digitalocean.com/debian jessie-updates main contrib non-free

然后更新您的来源：

sudo apt-get update

然后安装php5-fpm

sudo apt-get install php5-fpm

sudo nano /etc/apt/sources.list

加

deb http://packages.dotdeb.org wheezy all
deb-src http://packages.dotdeb.org wheezy all
deb http://packages.dotdeb.org wheezy-php56-zts all
deb-src http://packages.dotdeb.org wheezy-php56-zts all

保存并运行

sudo apt-get update
sudo apt-get upgrade
sudo apt-get install php5

完成后apt-get update，apt-get upgrade您必须使用以下命令进行安装：

sudo apt-get install php5
