You can use either of the following   include  class twitter php     or  require  class twitter php     Using require  or require once if you want to ensure the class is only loaded once during execution  will cause a fatal error to be raised if the file doesn t exist  whereas include will only raise a warning   See http   php net require and http   php net include for more details

Your code should be something like  require once  class twitter php      t   new twitter   t- gt username    user    t- gt password    password     data    t- gt publicTimeline

I suggest you also take a look at   autoload  This will clean up the code of requires and includes

Include a class example with the use keyword from Command Line Interface   PHP Namespaces don t work on the commandline unless you also include or require the php file   When the php file is sitting in the webspace where it is interpreted by the php daemon then you don t need the require line   All you need is the  use  line      Create a new directory  home el bin Make a new file called namespace example php and put this code in there    lt  php     require   home el bin mylib php       use foobarwhatever dingdong penguinclass        mypenguin   new penguinclass        echo  mypenguin- gt msg      gt   Make another file called mylib php and put this code in there    lt  php namespace foobarwhatever dingdong  class penguinclass        public function msg             return  It s a beautiful day chris  come out and play                       NO    SLAM    taka taka taka taka                  gt      Run it from commandline like this   el apollo   bin  php namespace example php   Which prints   It s a beautiful day chris  come out and play  NO    SLAM    taka taka taka taka    See notes on this in the comments here  http   php net manual en language namespaces importing php
