Ubuntu: How do I upgrade PHP version to the latest stable released version?



Question:

I'm using a system running on Ubuntu 12.04 LTS 64-bit OS.

I'm currently using following PHP version on this machine:

Command used to get the below info at terminal : php -v

Details I got are as below :

PHP 5.5.19-1+deb.sury.org~precise+1 (cli) (built: Nov 19 2014 19:32:34)   Copyright (c) 1997-2014 The PHP Group  Zend Engine v2.5.0, Copyright (c) 1998-2014 Zend Technologies      with Zend OPcache v7.0.4-dev, Copyright (c) 1999-2014, by Zend Technologies  

Now I want to upgrade my PHP software to version 5.5.20.

Before asking the question I tried following command:

sudo apt-get update  

Some information appeared. Then I again hit the following command:

php -v  

but still the PHP software didn't update.

How should I do this?


Solution:1

apt-get update updates only the package lists. To actually upgrade the packages you have to run:

sudo apt-get upgrade  

or

sudo apt-get dist-upgrade  

More info here.


If you ran the above commands but the packages still were not upgraded, probably you didn't add Ondřej Surý's PHP PPA to your system.

Run the following to add the PPA:

  • For PHP 5.5, PHP 5.6 and PHP 7.0:

    sudo apt-add-repository ppa:ondrej/php  
  • For PHP 5.4 (Deprecated, upgrade at least to PHP 5.5):

    sudo apt-add-repository ppa:ondrej/php5-oldstable  
  • For PHP 5.5 (Deprecated, use ppa:ondrej/php):

    sudo apt-add-repository ppa:ondrej/php5  
  • For PHP 5.6 (Deprecated, use ppa:ondrej/php):

    sudo apt-add-repository ppa:ondrej/php5-5.6  

Then update the package lists and perform the upgrade:

sudo apt-get update  

For PHP 5.5:

sudo apt-get install php5.5  

For PHP 5.6:

sudo apt-get install php5.6  

For PHP 7:

sudo apt-get install php7.0  

Release upgrade

If you want to install the latest PHP (for example PHP7) but you want to stick to the release's packages intead of hacking the sources around; and you want to do a full-release upgrade (for example you are in Ubuntu 14.04 -which does not have php7- and you want to go to Ubuntu 16.04 -which does- then you can do:

do-release-upgrade  

Now you should have the latest PHP version.


Solution:2

Run the following to add the PPA:

sudo apt-add-repository ppa:ondrej/php5  

By upgrading PHP from version 5.3 to 5.5, this may upgrade your Apache from version 2.2 to 2.4. So be careful.


Solution:3

For newest updating process use the following command

sudo LC_ALL=C.UTF-8 add-apt-repository ppa:ondrej/php  

Then run the following command in terminal

sudo apt-get update   

This is worked well when installing php 5.5,5.6 and 7.0

If there some errors this command will resolve the errors

sudo dpkg --configure -a  


Solution:4

If you want to upgrade only PHP 5.3 to 5.5 and do not want to upgrade the system, then you need to install apache 2.4 as well.

sudo apt-add-repository ppa:ondrej/apache2 -y  sudo add-apt-repository ppa:ondrej/php -y  sudo aptitude update  sudo apt-get install apache2 libapache2-mod-php5   

Beware about some changes in apache 2.4 related to require grant all.

Solution:5

On Ubuntu 14

Only this line is needed

sudo apt-add-repository ppa:ondrej/php5-5.6  

Then

sudo apt-get install php5  

This will trigger the PPA upgrade system
