How to Use PHP to Connect to a MySQL Database

Hello, developer php!

In this post, we will be discussing how to use the PHP programming language to connect to a MySQL database. As you may know, MySQL is a popular database management system that is often used in conjunction with PHP.

In order to connect to a MySQL database using PHP, you must first have a PHP script that contains the following code:


$link = mysql_connect('localhost', 'username', 'password');

if (!$link) {

die('Could not connect: ' . mysql_error());


echo 'Connected successfully';



In the above code, you will need to replace "username" and "password" with the appropriate values for your database. Once you have done this, you can then run the PHP script and it will connect to the MySQL database.

If you are new to PHP, or if you are new to connecting to databases, then you may be wondering how this code works. Essentially, the PHP script is connecting to the MySQL database using the mysql_connect() function. This function takes three parameters: the first is the name of the server where the MySQL database is located, the second is the username, and the third is the password. If the connection is successful, then the code will echo "Connected successfully" and the connection will be closed using the mysql_close() function.

If you are having trouble connecting to your MySQL database, then there are a few things that you can check. First, make sure that you are using the correct server name. If you are unsure of the server name, then you can try using the "localhost" value. Second, make sure that you are using the correct username and password. If you are unsure of these values, then you can check the documentation for your particular database. Finally, if you are still having trouble, then you can contact your web host or your database administrator for assistance.

Thank you for reading this post. We hope that you have found it to be helpful.
