Bash steps to install PHP7 in Cloud9

Install PHP7 on Cloud9

You can use phpbrew on Cloud9. I found that the standard installation process works fine, just run the commands below.

We first install the libmcrypt-dev package to avoid running into dependency issues during build:

$ sudo apt-get update
$ sudo apt-get install libmcrypt-dev
Next, we download phpbrew and move it to /usr/local/bin:

$ curl -L -O https://github.com/phpbrew/phpbrew/raw/master/phpbrew
$ chmod +x phpbrew
$ sudo mv phpbrew /usr/local/bin/
$ phpbrew init

# add this to your ~/.bashrc:
$ [[ -e ~/.phpbrew/bashrc ]] && source ~/.phpbrew/bashrc

$ phpbrew lookup-prefix ubuntu
Once set up, we install and load PHP 7:

$ phpbrew install 7.0 +default
$ phpbrew switch php-7.0.1

If you get an error like "Invalid PHP Argument...."
$ source $HOME/.phpbrew/bashrc

$ phpbrew use php-7.0.1
$ php -v
