Git branch in Ubuntu terminal

This is the code I added to ~/.bashrc around line 59. It affects the CLI prompt in the Ubuntu terminal in a number of ways.

1. It removes the username and computer name.
2. It adds the open Git branch, if one exists.
3. It adds a new line at the end, because some path's get very long, and don't give you much room to add your commands. 

parse_git_branch() {

 git branch 2> /dev/null | sed -e '/^[^*]/d' -e 's/* \(.*\)/(\1)/'

}

if [ "$color_prompt" = yes ]; then

 PS1='${debian_chroot:+($debian_chroot)}\[\033[01;32m\]\[\033[01;34m\]\w\[\033[01;32m\] $(parse_git_branch)\[\033[00m\]\n$ '

else

 PS1='${debian_chroot:+($debian_chroot)} $(parse_git_branch)\n$ '

Introduction to the PHP5 Command Line Interface (Ubuntu version)

So you'd like to write and run your PHP5 code without using a web browser. Where you run it from the command-line....

First make sure that the php5 cli is installed by typing this on the command line (terminal, shell, whatever you want to call it) :

sudo apt-get install php5-cli

Now it's time to create your first command line script to test. Use your favourite editor to create the following program and save it as hello.php:

<?php
echo 'hello world!';
?>

Now back to the command line. Make sure you are in the same directory as hello.php was saved. Now type:
php5 hello.php

You should see that hello world! is echo'd to the command line.

Now the following program:

• Takes the first number
• Assigns it to a variable ($first)
• Takes the second number
• Assigns it to a variable ($second)
• Adds the two numbers together and assigns them to the variable $answer
• Echo's the value of the variable $answer, then adds a line break.

<?php
echo 'Enter first number ';
$first = fgets(STDIN);
echo 'Enter second number ';
$second = fgets(STDIN);
$answer = $first + $second;
echo 'And the answer is '.$answer.PHP_EOL;
?>

Now you're ready to go.
