This means that the script will try to MySQL connect using the code provided, but if there is a problem, the code in the catch section will run. In the latter, you will find the try…catch. These are the variables and values we stated inside the dbconfig.php file, referenced one time by the line require_once in the databaseconnect.php. The DSN defines the type of database, the name of the database, and any other information related to the database if required. Save and Close it once you’re done.Ī PDO database connection requires you to create a new PDO object with a Data Source Name (DSN), Username, and Password. As always, don’t forget to replace the placeholder values with your database information. In the public_html, create a file named pdoconfig.php and insert the following code.This is similar to the previous method, but with a slight variation: The other method using PHP script to connect to MySQL is by using PDO. Using PDO to Connect a PHP Script to MySQL If not specified, the MySQL connections will close by itself once the script ends. The last part of the code is mysqli_close, which will simply close the connection to the database manually.
On the other hand, if the MySQL connection is successful, the code will print Connected successfully instead. By default, the MySQL connect error will say Connection failed followed by an exact error message describing the issue. This basically kills our script and gives us a connect error message that we have set. If the connection is not successful, the die() function is executed. In the code, we set our database details as values for those variables, so they can be passed into the function. Usually, we need four of them to establish a proper database connection: $servername, $database, $username, and $password. This is an internal PHP function to establish a new connection to a MySQL server.Īt the beginning of our code, we see a few variable declarations and values assigned to those variables. The main method used in this script is mysqli_connect(). Double-click to open the file and copy-paste the following lines of code into it.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.Head over to File Manager -> public_html.Using MySQLi to Connect a PHP Script to MySQLįollow these steps to use MySQLi to connect a PHP script to MySQL: For more details, contact your hosting provider so they could provide you with the correct information on what to use as the hostname. In contrast, if you are connecting to a database from a remote location (for example, your computer) you will have to use the IP address of the MySQL server. In general, this is the name that you’ll want to use if you uploaded your PHP script to the same server as the database. Hostinger uses “localhost” as its MySQL server’s hostname. You also need the correct server name or hostname for the configuration. This is where the MySQL database details you have previously saved come in handy. Whichever method you use, you will need the correct information so you can connect to the MySQL database you have made. It is also used to prevent SQL injection attacks when making changes to the database or inserting user-supplied input into a database query or statement. One of the most important features they both support is prepared statements, which accelerates the time needed for MySQL to execute the same query multiple times. The original mysql_ functions are deprecated and should not be used as they are unsafe and no longer being maintained or developed. Unlike MySQLi, PDO is only object-oriented and supports a number of different database types that use PHP, such as MySQL, MSSQL, Informix, and PostgreSQL. Meanwhile, MySQLi sees data as a set of interchangeable objects with functions, allowing users to add or remove data easily. The original MySQL breaks down a task into linear, step-by-step procedures, which makes it difficult to modify because you have to edit the code from the top.
MySQLi is both procedural and object-oriented, with the former being the attribute inherited from the older version of MySQL. MySQLi stands for MySQL Improved. It is a MySQL-exclusive extension that adds new features to a MySQL database’s interface. There are two methods to connect to a MySQL database using PHP: MySQLi and PDO.
