What are the potential pitfalls of using reserved words like "alter" in MySQL queries in PHP?

Using reserved words like "alter" in MySQL queries in PHP can lead to syntax errors or unexpected behavior because these words are already used by the database management system. To avoid this issue, you can use backticks (`) around the reserved word in your query to ensure it is treated as a column or table identifier rather than a keyword. 

$query = "SELECT * FROM `alter` WHERE id = 1";
$result = mysqli_query($connection, $query);

if ($result) {
    // Process the query result
} else {
    echo "Error: " . mysqli_error($connection);
}
