Are there any specific PHP functions or parameters that need to be adjusted for successful email sending post MySQL V5 upgrade?

After upgrading MySQL to V5, there may be changes in the database configuration that affect email sending functionality in PHP scripts. One common issue is with the connection parameters such as the hostname, username, password, and database name. To resolve this, ensure that the database connection parameters in the PHP script are updated to match the new MySQL V5 configuration. 

// Update the database connection parameters
$servername = "new_hostname";
$username = "new_username";
$password = "new_password";
$dbname = "new_database_name";

// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);

// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}
