How can reserved words in MySQL, like 'alter', impact the insertion of data from PHP forms?

Reserved words in MySQL, like 'alter', can impact the insertion of data from PHP forms if they are used as column names in SQL queries. To solve this issue, it is important to avoid using reserved words as column names and instead use backticks (`) to escape them in SQL queries. 

<?php
// Assuming $conn is the MySQL connection object

// Get form data
$data = [
    'name' => $_POST['name'],
    'email' => $_POST['email']
];

// Escape column names using backticks
$columns = implode('`, `', array_keys($data));
$columns = "`$columns`";

// Prepare SQL query
$sql = "INSERT INTO table_name ($columns) VALUES (?, ?)";
$stmt = $conn->prepare($sql);

// Bind parameters and execute query
$stmt->bind_param('ss', $data['name'], $data['email']);
$stmt->execute();

// Check for successful insertion
if ($stmt->affected_rows > 0) {
    echo "Data inserted successfully.";
} else {
    echo "Error inserting data.";
}

$stmt->close();
$conn->close();
?>
