When I was analysing about the different framework, they structure are little different but loading the classes are almost same way.
Why we need autoload for classes ?
Autoload use to load the classes, if you create the object for GetOutput class it will automatically call the filename. Thus filename and class name should be same. Without auto-loading we need to include the filename to create the object.
Let’s create simple class, which will print the value from the class.
GetOutput.php
class GetOutput { function __construct() { echo "Welcome to GetOutput"; } }
index.php
<?php // creating autoload function which will include the filename function __autoload($class_name) { include $class_name.".php"; } $obj = new GetOutput;
