Why is it important to avoid using quotes around column and table names in SQL queries?

Using quotes around column and table names in SQL queries can cause issues with portability and compatibility across different database systems. It is important to avoid using quotes to ensure that the queries can be executed successfully on any database system without modification. To solve this issue, you can use backticks (`) instead of quotes around column and table names in SQL queries.

$query = "SELECT `column1`, `column2` FROM `table` WHERE `column1` = 'value'";
