Let's talk about how to write thinkphp tool classes

thinkphp is a very easy-to-use and popular PHP framework. Its emergence simplifies a lot of work for developers and improves development efficiency. In the process of using the thinkphp framework, we often use various tool classes, so how to write thinkphp tool classes?

1. Create tool classes
Writing tool classes in thinkphp is very simple. Create an App/Lib/Util folder, and then create a new Util.class.php file under the folder. This is Our tool class.

2. Define the tool class and its methods
The following is the basic structure of a tool class:

namespace App\Lib;

class Util {

  public function getIP() {
    //获取客户端IP地址的代码
  }

  public function createUUID() {
    //生成UUID的代码
  }

}

The code here is for reference only. Through the above code we can see two functions getIP and createUUID, this is the most basic tool class.

3. Calling tool classes
Calling tool classes in thinkphp is also very simple. You only need to add the following code where you need to use tool classes:

use App\Lib\Util;

//调用工具类中的getIP()方法
$ip = Util::getIP();
//调用工具类中的createUUID()方法
$uuid = Util::createUUID();

4. Tool classes Notes in

1. Try not to use static variables and static methods in tool classes, as this is not very good for code reusability.
2. Try to use the singleton mode to ensure that the tool class is only instantiated once in the entire project.
3. The methods in the tool class should be as reusable as possible and can be applied in multiple scenarios.

To sum up, writing thinkphp tool classes is very simple. You only need to create a file and write relevant methods. We can use an example to simplify the writing of code and improve the reuse of code. sex.
