What are the best practices for mixing languages and casing conventions in SQL queries within PHP scripts?

When mixing languages and casing conventions in SQL queries within PHP scripts, it is best practice to use consistent casing for table and column names to avoid errors. One common approach is to use lowercase for all SQL keywords and uppercase for table and column names. This helps maintain readability and consistency in your code.

$query = "SELECT id, name FROM users WHERE status = 'active'";
