How can reserved words in MySQL affect the functionality of PHP scripts?

Reserved words in MySQL can cause issues in PHP scripts if they are used as column names or table names in SQL queries. To avoid conflicts, it is recommended to use backticks (`) around the reserved words in SQL queries to escape them. This ensures that MySQL interprets the reserved word as a column or table name rather than a keyword. 

// Example of using backticks to escape reserved words in MySQL queries
$columnName = 'select'; // Using a reserved word as a column name
$sql = "SELECT `{$columnName}` FROM table_name";
$result = mysqli_query($conn, $sql);
