How feasible is it to create a database of valid words (like a "Duden") to compare strings against for filtering purposes in PHP?

Creating a database of valid words for filtering purposes in PHP is feasible but may require a significant amount of time and resources to compile and maintain. One approach could be to use a pre-existing dictionary dataset or API to populate the database. Then, you can compare input strings against this database to filter out invalid words. 

// Example code snippet to check if a word is valid against a database of valid words

// Connect to the database
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "word_database";

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

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

// Function to check if a word is valid
function isValidWord($word, $conn) {
    $sql = "SELECT * FROM valid_words WHERE word = '$word'";
    $result = $conn->query($sql);

    if ($result->num_rows > 0) {
        return true;
    } else {
        return false;
    }
}

// Usage
$word = "example";
if (isValidWord($word, $conn)) {
    echo "Valid word";
} else {
    echo "Invalid word";
}

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