如何在 Debian GNU/Linux 7 上將 PHP 5.4 升級到 PHP 5.6 (wheezy)

我已將這些行添加到/etc/apt/sources.list

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

但是還是sudo apt-get update不要sudo apt-get upgrade碰php。

php --version還是

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

（更新）試試這個（Ubuntu）：

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

（更新） 對於 Debian Wheezy（使用 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)

（21/06/2017 更新） 對於 Debian 8 (jessie)

sudo nano /etc/apt/sources.list

添加以下儲存庫：

...
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

然後更新您的來源：

sudo apt-get update

然後安裝php5-fpm

sudo apt-get install php5-fpm
