PHP Database Connection Example Program

In this article we will show you the solution of php database connection example program, to establish a database connection, PHP provides the mysqli construct or mysqli connect() functions.

This function accepts six arguments and, in the event of success, needs to return a MySQL link identifier; otherwise, it returns FALSE.

It falls under the category of simple, minimal local servers used for website development.

Is if connection is successful,the assets are returned; otherwise, null is returned. To disconnect from a MySQL database, use the PHP mysqli close() function.IfIt returns true if the connection is closed; alternatively, it returns false.

The widely used database management system MySQL can support initiatives of all sizes.

One of its biggest selling points is its capacity to handle massive amounts of data without trying to break a sweat.

In PHP, there are three methods for connecting to a MySQL database via the backend:

  • Begin the XAMPP server by launching Apache and MySQL.
  • An XAMPP connection script should be created in PHP.
  • Start it in your local browser.
  • The database was successfully created using PHP code.
  • Using the XAMPP web server and PHP, the following path can be used to connect to the database.

Step By Step Guide On PHP Database Connection Example Program :-

<html>
   <head>
      <title>TalkersCode Connecting MySQL Server</title>
   </head>
   <body>
      <?php
         $dbhost = 'localhost';
         $dbuser = 'root';
         $dbpass = 'root@123';
         $mysqli = new mysqli($dbhost, $dbuser, $dbpass);
         if($mysqli->connect_errno ) {
            printf("Connect failed: %s<br />", $mysqli->connect_error);
            exit();
         }
         printf('Connected successfully.<br />');
         $mysqli->close();
      ?>
   </body>
</html>
  1. In the first step, we write, which informs the browser about the HTML version we are using. HTML documents begin with tags.
  2. We will describe the heading of the project using the tag.
  3. The webpage's content is described using the tag. This is where we write all of our website's content.
  4. Tags with short identifiers begin with "<?" and end with "?>". php.ini configuration files on servers should have short style tags enabled.
  5. Next, we create a host, a user, a password, and a MySQL database.
  6. We then print the statement.
  7. Then we launch XAMPP and begin running Apache, MySQL, and FileZilla.
  8. Next, create the PHP file and enter the PHP code necessary to create a database and then a table in it.
  9. Put the file in the XAMPP folder's htdocs folder as "data.php."
  10. Then, in your web browser, type localhost/data.php.
  11. Finally, the database is built and linked to PHP.

Conclusion :-

Prepared Statements are supported by both. Prepared Statements are crucial for the security of web applications because they guard against SQL Injection.

Data in a database are grouped together based on their relationship. PHP, Perl, Apache, MySQL, and Apache all make up XAMPP: cross-platform, Apache, MySQL, PHP, and Perl.

I hope this article on php database connection example program helps you and the steps and method mentioned above are easy to follow and implement.
