How can the use of reserved words as column names in a MySQL database impact PHP code?

Using reserved words as column names in a MySQL database can cause conflicts in PHP code when trying to retrieve or manipulate data from those columns. To solve this issue, it is recommended to enclose the reserved words in backticks (`) when referencing them in SQL queries in PHP code.

$query = "SELECT `column_name` FROM table_name";
$result = mysqli_query($connection, $query);

if ($result) {
    while ($row = mysqli_fetch_assoc($result)) {
        // Access data from the column_name column
    }
}
