How to call methods from other pages in PHP?

There are several ways to call methods from other pages in PHP.

1. Include or require statements are used to import code from other pages, allowing you to directly call the methods on that page. For example:

include 'other_page.php';
// 调用other_page.php中的方法
other_page_method();

1. To call methods from other pages, use namespaces. First, define a namespace in the page you want to call, then import the namespace using the “use” keyword and add the namespace prefix when calling the method. For example:

Define a namespace and method in other_page.php.

namespace MyNamespace;

function other_page_method() {
    // 方法实现
}

Import the namespace in the calling page and invoke the method.

use MyNamespace;

MyNamespace\other_page_method();

1. Utilize static methods in the class. Define the method you want to call as a static method, and when calling it, simply use the class name followed by the double colon operator. For example:

Define a static method in other_page.php file.

class OtherClass {
    public static function other_page_method() {
        // 方法实现
    }
}

Call a static method in the calling page.

OtherClass::other_page_method();

These are several common ways to call methods on other pages, choose the one that best suits your needs.
