Finally, the set_chirp() function reduces the text with $this->text and $this->length, and replaces the string with a link with $this->hashtags. Finally, specify the result html$this->chirp. At the bottom, use classes to create objects stored in the $chirp variable. A single parameter was passed to the class. If an object is created (or instantiated) in a class, run the creator function (\u construct()) in the class first__ With construct (), you can learn how to accept parameters passed to a class. Then perform multiple operations. Male $this-> directly set the value of hashtag_base$ Directly set the value of this->text. Set the length using a function called set_length(). This function is inside the class, so the $this set_chirp() function is referenced with $this to generate the final draft HTML. Therefore, you can reverse attributes within an object immediately after it is created. As you know, the final chirp html is stored in the $chirp attribute that can be accessed using $chirp->chirp. Don’t worry about not 100% understanding all this! It is recommended that you read the technical definitions of the elements used below, and then go back and reread this section. In the section on the elements of classes and objects, we will step back a bit and take a drier approach to viewing the components of objects and classes. The difference between objects and classes is that classes are blueprints based on the generated objects. Classes are defined after the class keyword using braces that contain the class name and class code. Load summary 125 eac6213f3bb67ef9510f8978f597 a class can contain two variables and functions, but they are called properties and methods within the class. By default, a class is a collection of properties and methods. To use properties and methods in a class, you must use the $this keyword for reference (for example, $this->get\u chirp()). To access a method or property from outside a class, you must reference it with the class name (for example, $object->get\u chirp()). Classes can contain several special functions. One of the functions is \u construct (), which is executed immediately after the object is created in the class. You can create any number of objects in a class. Load summary 125 eac6213f3bb67ef9510f8978f597 considering all the information, it is best to go back to the above example and reread it before proceeding to the following section. To use objects correctly, there is no single way to use objects correctly, so you must put quotation marks around the word \
