How can a PHP developer determine if the version of MySQL being used is compatible with certain functions like ORDER BY RAND()?

To determine if the version of MySQL being used is compatible with certain functions like ORDER BY RAND(), a PHP developer can check the MySQL version using the mysqli_get_server_info() function. This function returns the MySQL server version as a string, which can be compared against a minimum required version to ensure compatibility. 

// Get MySQL server version
$mysqli = new mysqli("localhost", "username", "password", "database");
$mysqlVersion = $mysqli->server_info;

// Check if MySQL version is compatible
$requiredVersion = "5.1.0";
if (version_compare($mysqlVersion, $requiredVersion) >= 0) {
    // MySQL version is compatible
    // Add code here to use ORDER BY RAND()
} else {
    // MySQL version is not compatible
    echo "MySQL version must be at least $requiredVersion for this functionality.";
}
