What are some common pitfalls when using PHP to send form data to a PHPmyAdmin database?

One common pitfall when sending form data to a PHPmyAdmin database using PHP is not properly sanitizing user input, which can leave your application vulnerable to SQL injection attacks. To solve this, always use prepared statements or parameterized queries to securely interact with the database. 

// Establish a connection to the database
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "database";

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

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

// Prepare a SQL statement using a parameterized query
$stmt = $conn->prepare("INSERT INTO table_name (column1, column2) VALUES (?, ?)");
$stmt->bind_param("ss", $value1, $value2);

// Set the form data to variables
$value1 = $_POST['input1'];
$value2 = $_POST['input2'];

// Execute the statement
$stmt->execute();

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