What are common syntax errors to watch out for when using PHP to insert data into a MySQL database?

Common syntax errors to watch out for when using PHP to insert data into a MySQL database include missing or incorrect quotation marks around values, forgetting to concatenate variables properly, and not escaping special characters. To avoid these errors, always double-check your SQL query strings and use prepared statements to prevent SQL injection attacks. 

// Example of inserting data into a MySQL database using prepared statements
$connection = new mysqli("localhost", "username", "password", "database");

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

$stmt = $connection->prepare("INSERT INTO table_name (column1, column2) VALUES (?, ?)");
$stmt->bind_param("ss", $value1, $value2);

$value1 = "John";
$value2 = "Doe";

$stmt->execute();

$stmt->close();
$connection->close();
