What steps can be taken to change the collation of tables in a MySQL database to UTF-8?

To change the collation of tables in a MySQL database to UTF-8, you can run a query to alter the table collation for each table in the database. This will ensure that all tables use the UTF-8 character set for storing data. 

<?php
// Connect to the database
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "database_name";
$conn = new mysqli($servername, $username, $password, $dbname);

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

// Change collation of tables to UTF-8
$sql = "ALTER DATABASE $dbname CHARACTER SET utf8 COLLATE utf8_unicode_ci";
if ($conn->query($sql) === TRUE) {
    echo "Database collation changed successfully";
} else {
    echo "Error changing database collation: " . $conn->error;
}

// Close connection
$conn->close();
?>
