get_server_version

In this article, we will focus on the mysqli_get_server_version() function in PHP, which returns the version number of the MySQL server. We will provide an overview of how it works and show examples of its use.

Introduction to the mysqli_get_server_version() function

The mysqli_get_server_version() function is a built-in PHP function that returns the version number of the connected MySQL server as an integer. This is useful when you need to verify the server version for a specific connection.

How to use the mysqli_get_server_version() function

Using the mysqli_get_server_version() function is straightforward. You call it on a valid MySQLi connection object. Here is an example:

How to use the mysqli_get_server_version() function?

<?php
$mysqli = mysqli_connect("localhost", "username", "password", "database");

if (!$mysqli) {
    die("Connection failed: " . mysqli_connect_error());
}

$server_version = mysqli_get_server_version($mysqli);

echo "Server version: " . $server_version;

mysqli_close($mysqli);
?>

In this example, we connect to a MySQL database using mysqli_connect(). We then verify the connection before calling mysqli_get_server_version() to retrieve the version number. The function returns an integer formatted as MAJOR * 10000 + MINOR * 100 + SUBMINOR (for example, 50729 represents MySQL 5.7.29). Finally, we output the result and close the connection.

Conclusion

The mysqli_get_server_version() function provides a reliable way to check the MySQL server version. Understanding its return format and proper usage helps ensure compatibility and stability in your database-driven applications.
