在类中包含php并使用include中的变量 - include php in class and use variable from include

include php in class and use variable from include

本文关键字：include 变量包含 php | 更新日期: 2023-12-29

我想从类中的db_connect.db访问$mysqli

db_connect.php

<?php
include_once("db.php");
$mysqli = new mysqli(DB_HOST, DB_USER, DB_PASS, DB_NAME);
mysqli_set_charset($mysqli,"utf8");
?>

class.php

class class{
    function __construct() {
        include_once 'db_connect.php';
    }
    function get()
    {
        if (!$mysqli->connect_errno) {
    }
    }
}

如果我在没有类的php函数中直接包含db_connect.php，我可以访问$mysqli

编辑我想在类的所有函数中访问$mysqli

感谢

您可以将其保存在一个类变量中：

class class{
    private $mysqli;
    function __construct() {
        include_once 'db_connect.php';
        $this->mysqli = $mysqli;
    }
    function get()
    {
        if (!$this->mysqli->connect_errno) {
        }
    }
}
