How can the PHP code be adjusted to properly execute the MySQL query without encountering collation issues?

The issue with collation arises when there is a mismatch between the collation settings of the database and the PHP script. To solve this, we can explicitly set the collation in the MySQL query to ensure compatibility. This can be done by adding the "COLLATE" clause with the appropriate collation type to the query.

$query = "SELECT * FROM table_name COLLATE utf8_general_ci WHERE column_name = 'value'";
$result = mysqli_query($connection, $query);

if ($result) {
    // Process the query result
} else {
    echo "Error executing query: " . mysqli_error($connection);
}
