Let’s see, here are some explanation for the main object from the PHP course from Codeacademy.

// The code below creates the class
class Person {
// Creating some properties (variables tied to an object)
public $isAlive = true;
public $firstname;
public $lastname;
public $age;
// Assigning the values
public function __construct($firstname, $lastname, $age) {
$this->firstname = $firstname;
$this->lastname = $lastname;
$this->age = $age;
}
// Creating a method (function tied to an object)
public function greet() {
return "Hello, my name is " . $this->firstname . " " . $this->lastname . ". Nice to meet you! :-)";
}
}
// Creating a new person called "boring 12345", who is 12345 years old ;-)
$me = new Person('boring', '12345', 12345);
// Printing out, what the greet method returns
echo $me->greet();
?> |
So we have a generic class, we have the function to “__construct”, and we have the method. A method will “do something”, is basically a function.
To do something with the class, we generate data for our class.
We call $me = new Person(“name”, “124”, “123”);
and to call the method greet from the function, we use this syntax.
echo $me->greet(); since $me is the variable that we used to add the data into our class/object.
