What potential problem could arise from using mysql_fetch_array in this context?

Using mysql_fetch_array in this context could potentially lead to security vulnerabilities, as it is deprecated and not recommended for use with modern versions of PHP. To solve this issue, you should switch to using mysqli or PDO for database interactions, as they offer better security features and support. By updating your code to use mysqli or PDO, you can ensure that your application is secure and up to date. 

// Connect to database using mysqli
$mysqli = new mysqli("localhost", "username", "password", "database");

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

// Query database using mysqli
$result = $mysqli->query("SELECT * FROM table");

// Fetch data using mysqli
while ($row = $result->fetch_assoc()) {
    // Process data
}

// Close connection
$mysqli->close();
