can someon please explain to me the difference between a class and a object?

Is a class the actual script and the instances that are pulled from the class are refered to as objects?

😕

A class script is just a script. An instantiated class is an object.

Once you have instantiated a class object...

$class = new Myclass;

.. you can refer to the class object properties and methods like this:

$class->myFunction();
$class->myvar;

In the calling script, you could instantiate several class objects with different arguments, if you needed to:

$class1 = newMyclass($arg1, $arg2);
$class2 = newMyclass($arg3, $arg4);

If a class is called with arguments there would be a constructor function which uses the arguments to declare some class properties.

A class can be seen as a blueprint of an object.
An object is an instance of a class.

For example, could could create an Animal class.
An instance of this Animal class would be the Dog object.

Classes consist of an integration of data and methods to deal with this data.
The Animal class could contain say, boolean hungry, string food, numeric consumed as data.
The methods isHungry() and eat() could be created in this Animal class.
Then the Dog object would be able to test if it is hungry, and would be able consume a certain amount of food.

Likewise a Pig object could be instantiated with the same abilities, but be set with different food. Maybe there would also be a consumption member variable (data), then based on this the consumed variable would increase until a certain level upon which the boolean variable hungry would be set to true.
