How can using reserved MySQL field names impact the execution of SQL queries in PHP?

Using reserved MySQL field names in SQL queries in PHP can lead to syntax errors or unexpected behavior. To avoid this issue, you should always use backticks (`) around field names that are reserved keywords in MySQL. 

<?php
// Example query with reserved field name
$field = "order";
$query = "SELECT `$field` FROM table_name";

// Execute the query
// $result = mysqli_query($connection, $query);
?>
