当我以前用php编程语言中使用netbeans连接phpmyadmin时，我遇到了一些错误

Question

This is my code for connecting to database:

$datbase=mysqli_connect("localhost:82","root"," ");
if(!$datbase)
{
    die("connection failed".mysqli_connect_error());
}

it shows me that

Warning: mysqli_connect(): MySQL server has gone away in C:\Program Files\apache24\Apache24\htdocs\PhpProject3\php_DataBase.php on line 9

Warning: mysqli_connect(): Error while reading greeting packet. PID=10848 in C:\Program Files\apache24\Apache24\htdocs\PhpProject3\php_DataBase.php on line 9

Warning: mysqli_connect(): (HY000/2006): MySQL server has gone away in C:\Program Files\apache24\Apache24\htdocs\PhpProject3\php_DataBase.php on line 9

line number 9 is database=mysqli_connect("localhost:82","root"," ")

Answer 1

Error in this line and also remove space in password

$datbase=mysqli_connect("localhost:82","root"," ");

You are not connecting to MySQL, but to Apache server. If you didn't change MySQL port just use

$datbase=mysqli_connect("localhost","root","","databaseName");
