In what scenarios should PHP developers prioritize using parentheses in SQL queries for clarity and accuracy?

Using parentheses in SQL queries is crucial when dealing with complex queries that involve multiple conditions and logical operators. By using parentheses, developers can ensure the query's logic is clear and accurate, especially when combining AND and OR operators. This practice also helps prevent unexpected behavior and ensures the query is executed as intended.

$query = "SELECT * FROM table WHERE (condition1 OR condition2) AND condition3";
