I have been using PhpStorm for more than 1 year. I love this IDE as its filled with awesome features. It provide so much of features which helps us to make our work much more easier. Here are the steps to install the IDE on 64 bit Ubuntu 14.04 operating system.
Uninstall the previous version of Oracle if you have installed previously :
sudo apt-get purge openjdk*
Installing Oracle Java 8:
sudo add-apt-repository ppa:webupd8team/java
sudo apt-get update
sudo apt-get install oracle-java8-installer
tar -xvf PhpStorm-2016.1.2.tar.gz
The last command will open up the PhpStorm IDE:
After the IDE have opened up, go to Tools and then select Create Desktop Entry option to create an icon to launch the IDE. Tools->Create Desktop Entry
Select OK in the appeared dialogue box
PhpStorm desktop entry will be created. The IDE is ready to open from the desktop for use.
