How can PHP be used to create a dynamic and user-friendly categorization system for organizing submitted links on a website?

To create a dynamic and user-friendly categorization system for organizing submitted links on a website using PHP, you can utilize a combination of HTML forms for user input, PHP for processing the form data, and a database to store and retrieve the categorized links. 

<?php
// Connect to the database
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "links_db";

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

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

// Process form submission
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    $link = $_POST['link'];
    $category = $_POST['category'];

    // Insert the submitted link into the database with the selected category
    $sql = "INSERT INTO links (link, category) VALUES ('$link', '$category')";

    if ($conn->query($sql) === TRUE) {
        echo "Link added successfully";
    } else {
        echo "Error: " . $sql . "<br>" . $conn->error;
    }
}

// Display form for users to submit links
echo '<form method="post" action="' . $_SERVER['PHP_SELF'] . '">
    <input type="text" name="link" placeholder="Enter link URL">
    <select name="category">
        <option value="tech">Tech</option>
        <option value="food">Food</option>
        <option value="travel">Travel</option>
    </select>
    <input type="submit" value="Submit">
</form>';

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