You have connected to the server and selected the database you want to work with. Thus it is a good practice to close the MySQL connection once all the queries are executed. And too many open MySQL connections can cause problems for your account. Your script will still run if you do not include this function. This is a very important function as it closes the connection to the database server. The only difference is, the mysqli () uses with PHP MySQLi object-oriented script, whereas the mysqliconnect () uses with PHP MySQLi procedural script, to do the job. If the script cannot connect it will stop executing and will show the error message “Unable to select database”.Īnother important PHP function is: $mysqli->close() This article is created to cover the two functions of PHP, that are: mysqli () mysqliconnect () Both functions are used to open a connection to the MySQL database server. With the above PHP uses the MySQL connection and with it – selects the database stored in the variable $database (in our case it will select the database “your_database”).
To select a database, you can use the following command: $mysqli->select_db($database) or die( "Unable to select database") This should be a database to which your username has access to. With this line PHP connects to the MySQL database server at localhost with the provided username and password.Īfter the connection is established you should select the database you wish to use. This can be done with the mysql_connect PHP function: $mysqli = new mysqli("localhost", $username, $password, $database) Next you should connect your PHP script to the database. You can replace the name with whatever you like just make sure it is using php as the extension.
Create a New File by clicking the icon from the upper menu. This will create three variables in PHP that will store the different MySQL connection details. Using MySQLi to Connect a PHP Script to MySQL Follow these steps to use MySQLi to connect a PHP script to MySQL: Head over to File Manager -> publichtml.
#PHP CONNECT TO MYSQL DATABASE SERVER PASSWORD#
You should replace your_username, your_password and your_database with the MySQL username, password and database that will be used by your script. If you need to change them later, this way you will be able to perform the change easily.
Connecting to a database via PHP is an extremely important step because if your script cannot connect to its database, your queries to the database will fail.Ī good practice when using databases is to set the username, the password and the database name values at the beginning of the script code.
