How to Reference PHP Class Member Functions

PHP classes provide programmers with reusable code that defines a section of a particular program. The class member functions execute statements within a class, such as a function in a "customer" class that provides information about a customer. You must create a variable that calls the class, then call the member function that runs the class code.

Instructions

1. Right-click the PHP file you want to use to call your class. Select "Open With," then double-click the PHP editor you used to create the class.

2. Create a variable and set it to the class name. The following code creates a PHP class variable:

   $class = 'myclass';

   Replace "myclass" with the name of your own PHP class.

3. Reference the PHP class member function. A class can contain several member functions, so you must know the function name to call it. Type the following code to reference the function:

   $class::viewCustomer();

   This code uses the class variable and calls the member function named "viewCustomer()." Replace "viewCustomer" with your own function name.

4. Save the file and run the PHP code in your editor. The debugger opens and runs the file in a Web browser, so you can see the changes made to the code file.
