How can the use of backticks affect the results of a MySQL query in PHP?

Using backticks in a MySQL query in PHP can help avoid syntax errors, especially when dealing with column names that are reserved keywords or contain special characters. It is considered a best practice to wrap column names with backticks to ensure the query runs smoothly without any issues.

php
$query = "SELECT `column1`, `column2` FROM `table_name` WHERE `column3` = 'value'";
