Php object-oriented: Member methods, member variables, class constants

Previously we talked about classes and objects and instantiated classes. for example, we created a person's class. However, people are not just attributes, but also behavior patterns, such as running, dancing, singing, and eating. So how can we implement these behaviors? Next, we will use our member method to implement it. The example of the previous lesson defines a person's class, Member method

Previously, we talked about the definition and instantiation of php classes. for example, we created a person's class.

However, people are not just attributes, but also behavior patterns, such as running, dancing, singing, and eating. So how can we implement these behaviors? Next, we will use our member method to implement it.

The example of the previous lesson defines a person's class and creates a running Member method.

Class Preson {public $ name; public $ age; public $ gender; public function Run () {// declare the member method echo "";}} // instantiate a class $ Preson1 = new Preson (); $ Preson1-> name = "demassiya"; // call the member method $ Preson1-> Run ();

This example is a simple call to create a member method.

Member variables

The variables in the class, also known as member variables, have been used in our previous examples. here we will introduce them to you.

Class Preson {public $ name; // defines the member variable public $ age ;}

In the above example, $ name is a member variable.

Class constant

If there are variables in the class, there will be constants. A constant is a constant value that does not change.

Define constants. We use const.

 Name = "Aesop"; echo 'I want to play'. $ character1-> name .'
'.' Skill is '. character: SKILLS;

The above example illustrates the definition and access methods of constants.
