php - mysql_pconnect 不工作

Question

我创建了一个 php 连接文件作为 explorecalirfornia.php 内容，如下所示。

#FileName="Connection_php_mysql.htm"
# Type="MYSQL"
# HTTP="true"
$hostname_explorecalirfornia = "localhost";
$database_explorecalirfornia = "explorecalirfornia";
$username_explorecalirfornia = "root";
$password_explorecalirfornia = "";
$explorecalirfornia = mysql_pconnect($hostname_explorecalirfornia, $username_explorecalirfornia, $password_explorecalirfornia) or trigger_error(mysql_error(),E_USER_ERROR);

我已使用命令将此 php 文件包含在我的页面中

<?php require_once('Connections/explorecalifornia.php'); ?> 

当我使用本地主机测试 php 代码时，抛出以下错误。

请帮助我完成我的教程。

  Either @mysql_pconnect($hostname_explorecalirfornia, $username_explorecalirfornia, $password_explorecalirfornia) or trigger_error(mysql_error(),E_USER_ERROR);  //@ infront of mysql_pconnect or use below written code

    $mysqli = new mysqli(HOST, USERNAME, PASSWORD, DBNAME);
    if ($mysqli->connect_errno) {
        echo "Failed to connect to MySQL: (" . $mysqli->connect_errno . ") " . $mysqli->connect_error;
     }
