How can reserved words in SQL queries impact the functionality of PHP scripts?

Reserved words in SQL queries can impact the functionality of PHP scripts by causing syntax errors or unexpected behavior. To avoid this issue, you can use backticks (`) around column and table names in your SQL queries to ensure that reserved words are treated as identifiers rather than keywords. 

<?php
// Example SQL query with backticks around column and table names
$sql = "SELECT `column1`, `column2` FROM `table` WHERE `condition` = 'value'";
$result = mysqli_query($connection, $sql);

// Rest of the PHP script
?>
