[英]include php in class and use variable from include
i want to access $mysqli from db_connect.db in my class我想从班级中的 db_connect.db 访问 $mysqli
db_connect.php 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类.php
class class{
function __construct() {
include_once 'db_connect.php';
}
function get()
{
if (!$mysqli->connect_errno) {
}
}
}
i can access $mysqli if i include the db_connect.php directly in a php function without a class如果我将 db_connect.php 直接包含在没有类的 php 函数中,我可以访问 $mysqli
edit and i want to access $mysqli in all functions of the class编辑,我想在类的所有函数中访问 $mysqli
thanks谢谢
you can save it in a class variable:您可以将其保存在类变量中:
class class{
private $mysqli;
function __construct() {
include_once 'db_connect.php';
$this->mysqli = $mysqli;
}
function get()
{
if (!$this->mysqli->connect_errno) {
}
}
}
