Learning OOPS Concept for beginner Part 1

How to start with oops php 

It is most Important to learn  OOPs PHP

1. For Advanced PHP we need to create two files 1st in index file and second is class file here it is
  (a) index.php
  (b) class_lib.php
 
2. After creating These two files we create a class in a file
    <?php
          class person {
         
          }         
    ?>

3. Add variable to your class this is also called add data to your class .One of the big difference
   <?php
          class person {
             var  $name;
          }         
    ?>
  
4. Add function method to your class And do not forget that in a class ,variable and properties
   are same
   <?php
          class person {
            var  $name;
            function  set_name($new_name) {
                      $this->name = $new_name;
                       }         
                 
            function  get_name() {
                      return $this->name;
                     }
           }
    ?>
