What is the common issue when trying to generate a JSON string from a MySQL query in PHP?

When trying to generate a JSON string from a MySQL query in PHP, a common issue is that the JSON output may not be formatted correctly due to special characters or encoding problems. To solve this issue, you can use the `json_encode()` function in PHP to properly encode the query result into a JSON string. 

// Connect to MySQL database
$connection = mysqli_connect("localhost", "username", "password", "database");

// Perform MySQL query
$query = "SELECT * FROM table";
$result = mysqli_query($connection, $query);

// Fetch query result and encode into JSON
$data = array();
while ($row = mysqli_fetch_assoc($result)) {
    $data[] = $row;
}

$json_string = json_encode($data, JSON_UNESCAPED_UNICODE);
echo $json_string;

// Close database connection
mysqli_close($connection);
