Objects in php oops

PHP is capable of functioning as an object-oriented programming language (or OOP). As such, it must be able to handle objects. An object is a data type that allows for the storage of not only data but also information on how to process that data. The data elements stored within an object are referred to as its properties, also sometimes called the attributes of the object. The information, or code, describing how to process the data compromises what are called the methods of the object.
Objects have two components to their construction. First, you must declare a class of object. It defines the structure of the object to be constructed. Then you instantiate the object, which means you declare a variable to be of a certain class and assign values to it appropriately.
Another way of looking at objects is that they allow you to create your own data types. You define the data type in the object class, and then you use the data type in instances of that class.
Yes, there is also an is_object() function to test whether a variable is on object instance.
