Writing Classes with PHP

Classes allow for the creation of objects that can contain multiple properties. The properties can then be pulled from the class using methods for a specific object. I recently wanted to create an array of objects, so I created an index.php page that looked similar to this.

<?php
include("class_lib.php");

for ($i=0; $i < 10; $i++){
// Use data pulled from a database or post data
   $array[$i] = new person ($name,$age,$address);
}
var_dump($array);
?>

I first include the class I am going to use to create the objects and then I create a new person for each instance of the array. I suggested that you get the data from post data or from a database.

The class will then look something like this.

<?php
class person{
  private $name;
  private $age;
  private $address;
  public function __construct($persons_name, $persons_age, $persons_address){
     $this->name = $persons_name;
     $this->age = $persons_age;
     $this->address = $persons_address;
  }

  // You can create set methods like

  public function set_name($new_name) {
     $this->name = $new_name;
  }

  //Or you can create get mehthods like

  public function get_name(){
     return $this->name;
  }

}
?>
