[PHP Learning] Daily use of inversion of control and dependency injection
The editor of this article will teach you about the use of inversion of control and dependency injection in PHP. If you are interested, come and take a look!
Inversion of control: control is given to your own class
Dependency injection: dependent on another class, I did not manually new it
<?php
/*我自己要用的类*/
class User {
private $name;
private $age;
public function __construct($name,$age){
$this->name=$name;
$this->age=$age;
}
public static function createResource($conf) {
return new self($conf['name'],$conf['age']);
}
public function says(){
echo $this->name;
}
}
$conf=array(
'name'=>'taoshihan',
'age'=>10
);
/*把这个地方放到一个类里,它就是个容器的概念了*/
/*体现了控制反转,所有的操作都是我自己的类里面进行的处理,不需要在调用的时候处理*/
/*这里也体现了依赖注入,就是我不手动去new对象了,我是在下面的方法中获取的对象*/
$user=call_user_func_array(array('User', "createResource"), array($conf));
$user->says();

How to execute an UPDATE query in php

Using MySQLi object-oriented method: establish a connection, preprocess UPDATE statements, bind parameters, execute and check the results, and finally close the resource. 2. Using MySQLi procedure method: connect to the database through functions, prepare statements, bind parameters, perform updates, and close the connection after processing errors. 3.
