How can reserved keywords in MySQL cause errors when used as field names in PHP, and what are best practices to handle this issue?

Reserved keywords in MySQL can cause errors when used as field names in PHP because they conflict with the SQL syntax. To handle this issue, you can enclose the field names in backticks (`) in your SQL queries to ensure they are treated as identifiers rather than keywords. 

<?php
// Example query with a reserved keyword as a field name
$field_name = "order";
$query = "SELECT `{$field_name}` FROM table_name";

// Execute the query using your database connection
$result = mysqli_query($connection, $query);

// Fetch and process the results
while ($row = mysqli_fetch_assoc($result)) {
    // Process the data here
}
?>
