Install multiple versions of php

If you are a developer, something you need to install two different versions of PHP for testing or coding based on required platform. But install two parallel versions is not the easy task, we need some of support packages.

To install multiple versions of PHP, we need two packages

phpenv: https://github.com/CHH/phpenv for setup separate rbenv environment.
php-build: a utility for building versions of PHP to use them side by side with each other. ( https://github.com/chh/php-build )

First, we need install the phpenv

git clone [email protected]:CHH/phpenv.git
cd phpenv
bash bin/phpenv-install.sh

The phpenv-install.sh command sets up a separate rbenv environment for usage with PHP. This environment is stored in the $HOME/.phpenv directory and contains a phpenv executable which sets the RBENV_ROOT environment variable to $HOME/.phpenv .

Secondly, we install the php-build

git clone git://github.com/CHH/php-build.git
cd php-build
sudo bash install.sh

Finally, install other php version

sudo apt-get install libxml2-dev
sudo apt-get install libcurl4-gnutls-dev
sudo apt-get install libmcrypt4 libmcrypt-dev
sudo apt-get install libreadline-dev
sudo apt-get install libtidy-dev
sudo apt-get install libxslt1-dev
sudo php-build -i development 5.3.28 $HOME/.phpenv/versions/5.3.28

phpenv versions
phpenv rehash
phpenv global 5.4.9
php –version
phpenv global system
php –version
