How can syntax errors related to combining comparison operators in SQL queries be identified and resolved when using PHP?

When combining comparison operators in SQL queries in PHP, syntax errors can occur if the operators are not properly formatted. To identify and resolve these errors, carefully review the query for any misplaced or missing operators. Additionally, ensure that the query is properly enclosed in quotation marks and that the comparison operators are used correctly within the SQL syntax.

$query = "SELECT * FROM table_name WHERE column_name > 10 AND column_name < 20";
