Zend-Setup on Ubuntu 13.10

To setup zend on ubuntu 13.10(my version)

We need to download its latest framework from
http://www.zend.com/en/company/community/downloads

Zend 1.12.5 is latest as of writing this post

Next unzip and place the same in your home directory and delete all folders except bin and library

Next we need to tell our php to include Zend library so in our php.ini

(found in /etc/php5/apache2/php.ini)

perform following actions

Add
include_path=".:/home/gaurav/ZendFramework-1.12.5/library"
if you find include_path  not used or

Append "/home/gaurav/ZendFramework-1.12.5/library" to current path if include_path is defined (check it's commented by default)

Save and Close

Next move to root and using root privileges(sudo)

create a file 

cd /

nano .bashrc

and add code 

"alias zf=/home/gaurav/ZendFramework-1.12.5/bin/zf.sh"

Save and exit

Next Source .bashrc by following command

"source .bashrc"

now run zf command

If you get an output as follows

 An Error Has Occurred
