What is SET NAMES utf8?

SET NAMES utf8 is a MySQL command that sets the character set to be used for the connection. This ensures that the data being transferred between MySQL and PHP is in the same character set, preventing any encoding issues. UTF-8 is a universal character set that supports a wide range of characters, making it a popular choice for web development.

How to use SET NAMES utf8 in PHP

To use SET NAMES utf8 in PHP, you can include the following code at the beginning of your script:

$dsn = 'mysql:host=localhost;dbname=mydatabase';
$username = 'myusername';
$password = 'mypassword';

$options = array(

try {
    $db = new PDO($dsn, $username, $password, $options);
} catch (PDOException $e) {
    echo 'Connection failed: ' . $e->getMessage();

The above code uses the PHP Data Objects (PDO) extension to connect to a MySQL database. The SET NAMES utf8 command is included in the $options array, which is passed to the PDO constructor. This ensures that the character set is set correctly for the connection.


Using SET NAMES utf8 is an effective way to optimize data integration between MySQL and PHP. By ensuring that the character set is consistent between the two, you can prevent any encoding issues and ensure that your data is transferred seamlessly.
