PHP Password Change Page

We need to use passwords when performing many business operations. The issue of password confidentiality has always been a very important topic. When it comes to data security, passwords should be encrypted using the highest level of protection. But even if your password is impeccable, if you forget it, your data will become inaccessible. In this case, we need a password change tool to help us reset a new password to ensure that the data can be used in a timely manner.

In PHP, creating a password change page is relatively simple. The following are the main steps and implementation process.

Step 1 - Establish a database connection

The first step is to establish a database connection. Here we can use MySQL database. In PHP's MySQL function, we can use the mysqli_connect() function to connect to the MySQL database.

Sample code:

$dbhost = 'localhost'; //Database host name
$dbname = 'mydatabase'; //Database name
$dbuser = 'root' ; //Database username
$dbpass = ''; //Database password

$conn = mysqli_connect("$dbhost", "$dbuser", "$dbpass") or die ("Connect Error");

mysqli_select_db($conn,"$dbname") or die ("Cannot connect to the database");

If the connection fails, "Connection error" or " Cannot connect to database" and other prompt messages.

Step 2 - Create a password change form

We need to create a password change form in HTML.
