What are common challenges faced by PHP beginners when trying to create a survey manager?

One common challenge faced by PHP beginners when creating a survey manager is handling form submissions and processing user input. To solve this, beginners can use PHP to validate and sanitize user input before storing it in a database. 

// Check if form is submitted
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    // Validate and sanitize user input
    $survey_answer = filter_input(INPUT_POST, 'survey_answer', FILTER_SANITIZE_STRING);

    // Store the sanitized input in a database
    // Example code to insert data into a MySQL database
    $conn = new mysqli($servername, $username, $password, $dbname);
    $sql = "INSERT INTO survey_answers (answer) VALUES ('$survey_answer')";
    $conn->query($sql);
    $conn->close();
}
