How to include a class in PHP [closed]

Your code should be something like

require_once('class.twitter.php');$t = new twitter;$t->username = 'user';$t->password = 'password';$data = $t->publicTimeline();

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

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.

1. Create a new directory /home/el/bin

2. Make a new file called namespace_example.php and put this code in there:

   <?php    require '/home/el/bin/mylib.php';    use foobarwhatever\dingdong\penguinclass;    $mypenguin = new penguinclass();    echo $mypenguin->msg();?>

3. Make another file called mylib.php and put this code in there:

   <?phpnamespace foobarwhatever\dingdong;class penguinclass {    public function msg() {        return "It's a beautiful day chris, come out and play! " .                "NO!  *SLAM!*  taka taka taka taka.";     }   }?>   

4. Run it from commandline like this:

   el@apollo:~/bin$ php namespace_example.php 

5. Which prints:

   It's a beautiful day chris, come out and play!NO!  *SLAM!*  taka taka taka taka
