How to call class method in php? Step by step explanation

How to call class methods in php? The following article will introduce to you the steps required to call a class method. I hope it will be helpful to you!

In PHP, calling a class method requires the following steps.

1. Define a class

In PHP, you first need to define a class. A class is a template containing properties and methods, used to instantiate objects. The following is an example of a simple PHP class:

class MyClass {
  public $myVariable;
  
  public function myMethod() {
    //...
  }
}

This class contains a property myVariable, and a method myMethod().

2. Instantiate objects

The process of creating objects through classes is called instantiation. In PHP, instantiating objects can be done through the new keyword:

$obj = new MyClass();

Through this process, we create an object of the MyClass class. Here's how to assign values ​​to object properties:

$obj->myVariable = "Hello World";

At this time, the value of $obj->myVariable is "Hello World".

3. Call class methods

Different from attributes, class methods are used to perform some specific operations. In PHP, you can call a class method in the following way:

$obj->myMethod();

In this example, the myMethod() method will be called and perform its defined operation.

Usually, class methods need to provide some parameters to perform operations. In PHP, you can pass parameters to a method as follows:

$obj->myMethod($param1, $param2);

Next, you can use these parameters in the method to perform specific operations.

Summary

The above are the steps for calling class methods in PHP. First, you need to define a class and create objects. Then, access the properties and methods of the class through the object. Finally, you can pass parameters to methods to perform specific operations. If you want to learn more about PHP classes and objects, you can refer to PHP's official documentation and PHP tutorials.
